constrain the tasks it creates to run on Nomad client agents which have the `java` driver enabled and at least Java 7. +The tasks use Nomad's `exec` driver to run Spark scripts on those nodes, and the

name or URL of a docker image to use to run Spark Nomad tasks. +The tasks use Nomad's `docker` driver to run Spark scripts in a container created from this image. +The image should contain a JRE, and

+## Client Mode + +In client mode (the default deployment mode), +the Spark application is either directly started by the user, or run directly by `spark-submit`, +so the application driver runs on a machine that is not necessarily in the Nomad cluster. +The driver's SparkContext creates a Nomad job to run Spark executors. +The executors connect to the driver and run Spark tasks on behalf of the application. +When the driver's SparkContext is stopped, the executors are shut down. + +![](img/nomad-client-mode.png) + +Note that the machine running the driver or spark-submit needs to be reachable from +the Nomad clients so that the executors can connect to it. + +In client mode, application resources need to start out present on the submitting machine, +so jars (both the primary jar and those added with the `--jars` option) can't be specified using `http:` or `https:` URLs. +You can either use files on the submitting machine (either as raw paths or `file:` URLs), +or use `local:` URLs to indicate that the files are independently available on both +the submitting machine and all of the Nomad clients where the executors might run. + +In this mode, the spark-submit invocation doesn't return until the application has finished running, +and killing the spark-submit process kills the application. + +For example, to submit an application in client mode: + + $ ./bin/spark-submit --class org.apache.spark.examples.SparkPi \ + --master nomad \ + --distribution http://example.com/spark.tgz + lib/spark-examples*.jar \ + 10 + +## Cluster Mode + +In cluster mode, the `spark-submit` process creates a Nomad job to run the Spark application driver. +The driver's SparkContext then adds Spark executors to the Nomad job. +The executors connect to the driver and run Spark tasks on behalf of the application. +When the driver's SparkContext is stopped, the executors are shut down. + +![](img/nomad-cluster-mode.png) + +In cluster mode, application resources need to be hosted somewhere accessible to the Nomad cluster, +so jars (both the primary jar and those added with the `--jars` option) can't be specified using raw paths or `file:` URLs. +You can either use `http:` or `https:` URLs, or use `local:` URLs to indicate that +the files are independently available all of the Nomad clients where the driver and executors might run. + +Note that in cluster mode, the nomad master URL needs to be routable from both the submitting machine and +the Nomad client node that runs the driver. If the Nomad cluster is integrated with Consul, +you may want to use a DNS name for the Nomad service served by Consul. + +For example, to submit an application in cluster mode: + + $ ./bin/spark-submit --class org.apache.spark.examples.SparkPi \ + --master nomad \ + --deploy-mode cluster \ + --distribution http://example.com/spark.tgz + http://example.com/spark-examples.jar \ + 10 + +### Monitoring Output + +By default, `spark-submit` in cluster mode will simply submit your application to the Nomad cluster. +You can use the `spark.nomad.cluster.monitorUntil` configuration property (set by `spark-submit`'s `--monitor-until` flag) +to have spark-submit monitor the job after submitting it, and even tail its log until the job completes. + +In any case, once the job has been submitted to Nomad, killing spark-submit won't stop the spark application, +as it runs independently in the Nomad cluster. + +### Spark UI + +In cluster mode, if `spark.ui.enabled` is `true` (as by default), the Spark UI will be +dynamically allocated a port. The UI will be exposed by Nomad as a service, +and the UI's URL will appear in the Spark driver's log. + +The Spark UI stops being served when the application finishes. +This can sometimes be frustrating when debugging an application. +You can delay the stopping of the UI by setting `spark.ui.stopDelay` duration, e.g. "5m" for 5 minutes. +Note that this will cause the driver process to continue running. +You can force a delayed stop to proceed immediately on the "Jobs" page of the web UI, +or by sending + + +# Remote URLs + +Nomad uses [go-getter](https://github.com/hashicorp/go-getter) to download artifacts, +which allows you to embed checksums in HTTP/S URLs. +Using checksums is recommended, as it allows Nomad to both verify the integrity of a file, +and use the checksum as a cache key to avoid re-downloading unchanged files. +The checksums take the form of a query string parameter of the form `checksum=type:value`, +where `type` is a hash type and `value` is the checksum value. +See the [go-getter checksumming documentation](https://github.com/hashicorp/go-getter#checksumming) +for details. + + +# Nomad Job Customization + +By default, Nomad will start with a blank job, and starts adding to it. +When running in cluster mode, it will add a task group for the driver, +containing a task (with a "spark.nomad.role" = "driver" meta value) to run the driver. +The driver then adds a task group to run its executors. +The executor task group will contain a task (with a "spark.nomad.role" = "executor" meta value) to run the executor, +and if the shuffle service is enabled (as with [dynamic allocation](#dynamic-allocation-of-executors)), also a task (with a "spark.nomad.role" = "shuffle" meta value) to run the shuffle service. + +The following incomplete HCL job specification gives an idea of the structure of a Nomad job created by Spark. + +~~~ .hcl +job "structure" { + meta { + "spark.nomad.role" = "application" + } + + # A driver group is only added in cluster mode + group "driver" { + task "driver" { + meta { + "spark.nomad.role" = "driver" + } + } + } + + group "executors" { + count = 2 + + task "executor" { + meta { + "spark.nomad.role" = "executor" + } + } + + # shuffle service tasks are only added when enabled (as it must be when using dynamic allocation) + task "shuffle-service" { + meta { + "spark.nomad.role" = "shuffle" + } + } + } +} +~~~ + +There are two ways to customize the Nomad job, task groups and tasks that Spark creates. +You can provide a job template that Spark will use as a starting point for creating its Nomad job, allowing you to customize almost any aspect of the job. +You can also set Spark configuration properties to override e.g. how many resources Spark should reserve for its Nomad tasks. + +The order of precedence for settings is as follows: +1. Explicitly set configuration properties. +2. Settings in the job template if provided. +3. Default values of the configuration properties. + + +## Using a Job Template + +Rather than having Spark create a Nomad job from scratch to run your application, +you can set the `spark.nomad.job.template` configuration property (set by `spark-submit`'s `--nomad-template` flag) +to the path of the file containing a template job specification. +There are two important things to note here: +- The template must be in the format of a [JSON job specification](https://www.nomadproject.io/docs/http/json-jobs.html). + Nomad job specifications are normally [written in HCL](https://www.nomadproject.io/docs/job-specification/) and converted to JSON + by the `nomad` command-line tool. You can convert an HCL jobspec to JSON by running `nomad run -output `. +- `spark.nomad.job.template` should be set to a path on the submitting machine, *not* to a URL (even in cluster mode). + The template does not need to be accessible from driver or executors. + +Using a job template you can override Spark's default resource utilization, +add additional metadata or constraints, set environment variables, add sidecar tasks to the driver or executor task groups, +add additional task groups of your own, etc. + +The template does not need to be a complete Nomad jobspec, as Spark will add everything necessary to run your Spark application. +E.g., your template might set some job metadata, but not contain any task groups, +making it an incomplete Nomad jobspec but still a valid template to use with Spark. + +When setting properties in the job Spark creates from your template, the value precedence is as follows: +1. Values from Spark properties +2. Values in the job template +3. Default values for Spark configuration properties + +E.g. the job priority is controlled by the `spark.nomad.priority` configuration property, which has a default of 40. +If a value is specified for that property (e.g. on the commandline, in `spark-defaults.conf`, etc.), that value will be used. +Otherwise if the template contains a value for the priority, the template's value will be used. +If neither of these sources provides a value, the default of 40 will be used. + +Conceptually, this is how Spark uses the job template: + +1. Identify the template task group for Spark executors, of which there should be at most one, + as a group containing tasks with a "spark.nomad.role" meta value of "executor" or "shuffle". + If there is such a group, it is removed from the job and used as a template for executors. + +2. Identify the template task group for the Spark driver, of which there should be at most one, + as a group containing a task with a "spark.nomad.role" meta value of "driver". + If not running in cluster mode, this task group is removed from the job and discarded. + +3. Proceed as normal, but using the provided job, driver task group, and executor task group template + as the starting point for the task groups that are normally generated. + +Here's an example of a small HCL template that sets a metadata value on the job and an environment +variable for executors: + +~~~ .hcl +job "template" { + meta { + "foo" = "bar" + } + group "executor-group-name" { + task "executor-task-name" { + meta { + "spark.nomad.role" = "executor" + } + env { + BAZ = "something" + } + } + } +} +~~~ + +Note that this is only a partial jobspec and not fully runnable. But it is a valid template, and can be converted to JSON with `nomad run -output `. +The job name is always set at runtime, so the "template" name is just a syntactically necessary placeholder and will be overridden. +Also note that it is the "spark.nomad.role" = "executor" meta value on the driver task that tells Spark that the "driver-group-name" task group is the template for executors; +the names of the group and task can be whatever you like. + + +## Resource Allocation + +Resource allocation can be configured using a job template or through configuration properties. + +Configuring resources using a template would look something like this (this HCL syntax; see the section above on converting this to JSON): + +~~~ .hcl +job "template" { + group "group-name" { + task "task-name" { + meta { + "spark.nomad.role" = "role" # this would be "driver", "executor", or "shuffle", as appropriate + } + + resources { + cpu = 2000 + memory = 2048 + + network { + mbits = 100 + } + } + } + } +} +~~~ + +Resource-related configuration properties are covered below: + +### Memory + +The standard Spark memory properties will be propagated to Nomad to control task resource allocation: +`spark.driver.memory` (set by `spark-submit`'s `--driver-memory` flag) and +`spark.executor.memory` (set by `spark-submit`'s `--executor-memory` flag). +You can additionally specify `spark.nomad.shuffle.memory` to control how much memory Nomad allocates to shuffle service tasks. + +### CPU + +Spark sizes its thread pools and allocates tasks based on the number of CPU cores available. +Nomad manages CPU allocation in terms of processing speed rather than number of cores. + +When running Spark on Nomad, you can control how much CPU share Nomad will allocate to tasks using +the `spark.nomad.driver.cpu`, `spark.nomad.executor.cpu` and `spark.nomad.shuffle.cpu` properties +(or `spark-submit`'s `--driver-cpu` and `--executor-cpu` flags). + +When running on Nomad, executors will be configured to use one core by default, +meaning they will only pull a single 1-core task at a time. +You can setting the `spark.executor.cores` property (set by `spark-submit`'s `--executor-cores` flag) +to allow more tasks to be executed concurrently on a single executor. + +### Network + +Nomad doesn't restrict the network bandwidth of running tasks, +bit it does allocate a non-zero number of Mbit/s to each task and uses this when bin-packing task groups onto Nomad clients. +Spark defaults to requesting the minimum of 1 Mbit/s per task, but you can change this with the +`spark.nomad.driver.networkMBits`, `spark.nomad.executor.networkMBits`, and `spark.nomad.shuffle.networkMBits` properties. + +### Log Rotation + +Nomad performs log rotation on the `stdout` and `stderr` of its tasks. +You can configure the number number and size of log files it will keep for driver and executor task groups using +`spark.nomad.driver.logMaxFiles` and `spark.nomad.executor.logMaxFiles`. + + +# Logs + +Nomad clients collect the stderr and stdout of the tasks that they run, +and the nomad CLI or API can be used to inspect them, as documented in Nomad's documentation on +[Accessing Logs](https://www.nomadproject.io/docs/operating-a-job/accessing-logs.html). + +Links to the stderr and stdout of the executors tab of the Spark UI. +In cluster mode, the stderr and stdout of the driver application can be found there as well. + +The Log Shipper Pattern described in the "Accessing Logs" link above uses sidecar tasks to forward logs to a central location. +This can be done [using a job template](#using-a-job-template) along the following lines: + +~~~ .hcl +job "template" { + + group "driver" { + task "driver" { + meta { + "spark.nomad.role" = "driver" + } + } + task "log-forwarding-sidecar" { + # sidecar task definition here + } + } + + group "executor" { + task "executor" { + meta { + "spark.nomad.role" = "executor" + } + } + task "log-forwarding-sidecar" { + # sidecar task definition here + } + } + +} +~~~ + + +# Dynamic Allocation of Executors + +By default, the Spark application will use a fixed number of executors. +Setting `spark.dynamicAllocation` to `true` enables Spark to +add and remove executors during execution depending on the number of Spark tasks scheduled to run. +As described in [Dynamic Resource Allocation](http://spark.apache.org/docs/latest/job-scheduling.html#configuration-and-setup), +dynamic allocation requires that `spark.shuffle.service.enabled` be set to `true`. + +On Nomad, setting `spark.shuffle.service.enabled` to `true` adds an additional +shuffle serivce Nomad task to the executors' task group. This results in a +one-to-one mapping of executors to shuffle services. + +When the executor exits, the shuffle service continues running so that it can serve any results produced by the +executor. Note that due to the way resource allocation works in Nomad, +the resources allocated to the executor Nomad task aren't freed until the shuffle service +is also finished, meaning that they will remain allocated until the application has finished. +This may improve in the future. + + +# Python and R + +There is basic support for running Spark applications written in Python and R on Nomad, +including the `pyspark` and `sparkR` interactive modes. + +For example, running a python Spark application on Nomad: + +``` +bin/spark-submit \ + --master nomad \ + --distribution http://example.com/spark.tgz \ + examples/src/main/python/pi.py +``` + +For example, running a sparkR interactive mode with executors on Nomad: + +``` +bin/sparkR \ + --master nomad \ + --distribution http://example.com/spark.tgz +``` + +Note that the python or R runtime must be installed on the Nomad clients; +if these are only present on some client, you can use constraints (documented above) +to ensure your task groups run on these clients. + + +# Configuration + +Most of the configuration properties are the same for Spark on Nomad as for other deployment modes. +See the [configuration page](configuration.html) for more information on those. + +These are configuration properties that are specific to running Spark on Nomad. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
