Crane, a simple Storm-like streaming processing system, CS 425 MP4, implemented by Grp#29 Baohe Zhang & Kechen Lu. It implemented a Storm-like system, which includes spout-bolt task distribution-running and reliability schemes for failover. It also integrates the SDFS to having input files or results to be availible for all nodes in the cluster.
- Language: Golang
- Tested Platform: macOS 10.13, CentOS 7
- Code file structure
/bolt: Framework for users to write the bolt task and set initial information /core: Main code relating to the crane framework, it includes the /core/supervisor: supervisor for distributing the tasks to /core/boltworkers or core/spoutwokers /core/driver: Master node to process topology submitted from the client, and then build the topopogy, distribute then to supervisors with bolts or spouts /topology: topology framework for user application to submit the topology as client /examples: Three examples for the Crane system /scripts: Helper scripts for updating git repo or start/stop process /spout: spouts task interface for user application to submit
To build the Crane project, we will go to the driver directory and supervisor directory to build separately. Just run
$ cd ./core/driver
$ go build
$ cd ./core/supervisor
$ go buildThey are core parts of Crane system which play the topology building and distributing role. To deploy on the each machine of the cluster, we have to git clone this repo like below. To simply the repo update and build in the VM cluster, we have a easy-to-use script, each time we push a new commit to remote repo then run.
$ git clone git@gitlab.engr.illinois.edu:baohez2/crane.git
$ ./scripts/update_all.shWe have examples in the /examples folder. There are three examples. For example, we can enter the example/join folder. Just run go build . Then when we want to submit a topology with bolts and tasks, just run this application.
To run our Crane daemon, go to the ./driver/ or ./supervisor/ directory. We can use ./supervisor -h to get command help for starting the supervisors. We run the driver(master) deamon like below
$ cd ./core/driver
$ ./driver

Then we may want to start the daemon of supervisor which would actually spawning worker pool to execute the spout or bolt tasks. Use ./supervisor -h to see the arguments. And we run the supervisor like below to connect the master node vm 1.
$ cd ./core/supervisor
$ ./supervisor -h
flag needs an argument: -h
Usage of ./supervisor:
-h string
Driver's IP address (default "127.0.0.1")
-vm int
VM index in cluster
$ ./supervisor -vm 1

2018/12/02 22:18:09 Send Join Request
To run client, just run the example user application in the examples. It would put the needed file first into the SDFS. And submit the topology to driver(master) node.
$ $ ./join
