Databricks API for Scala

This tiny library wraps official Databricks API v2.0 into an easy to use tool to do groundwork for uploading your code to databricks and creating jobs there. Supported API methods are:

• Dbfs: put, read, getStatus, delete
• Jobs: create, reset, delete, get, list

Other methods may be implemented in the latest versions of the library.

Installation

for SBT, add to your build.sbt:

libraryDependencies += "io.findify" %% "databricks-scala-api" % "0.3.1"

The library supports both scala 2.10 and 2.11 (but keep in mind that databricks in 2016 still does not support 2.11).

Usage

Uploading jar to databricks dbfs:

val dbc = new Databricks(Auth(host, user, pass))
val jar = Files.readAllBytes(Paths.get("path_to_jar.jar"))
dbc.dbfs.put(jar, s"/FileStore/job-jars/foo.jar")

all the API methods return Future, but some of the replies are empty on success.

Updating job definition:

  dbc.jobs.reset(123, Job(
    name = "hello-world",
    new_cluster = Some(Cluster(
      spark_version = "1.6.1-ubuntu15.10-hadoop2",
      node_type_id = Some("memory-optimized"),
      aws_attributes = AWSAttributes(availability = Some("ON_DEMAND"), zone_id = Some("us-east-1a")),
      num_workers = 1
    )),
    libraries = Some(List(
      Library(jar = Some(s"dbfs:/FileStore/job-jars/hello-world.jar")),
      Library(maven = Some(Maven("ch.qos.logback:logback-classic:1.1.7"))),
      Library(maven = Some(Maven("org.slf4j:slf4j-api:1.7.21"))),
      Library(maven = Some(Maven("com.logentries:logentries-appender:1.1.32")))
    )),
    spark_jar_task = Some(JarTask(
      jar_uri = Some(s"hello-world.jar"),
      main_class_name = s"com.example.Main"
    )),
    email_notifications = Notifications(Some(List("monitoring@example.com"))),
    timeout_seconds = 300,
    max_retries = Some(3),
    schedule = Some(CronSchedule(
      quartz_cron_expression = s"0 0 6 * * ?",
      timezone_id = "UTC"
    ))
  ))

After all, close the client:

dbc.close()
