Veena Basavaraj updated SQOOP-1532:
-----------------------------------
Description: (was: Here are the things this ticket should address
1. Refactor the submit() in JobManager ( it is way too long for any good unit
testing to happen)
2. Revisit the Execution Engine and Submission Engine relationship in the code.
ExecutionEngine api should probably not create a submissionRequest. It should
be the inverse. The Submission Engine is an abstraction of a JobTracker/ YARN/
Mesos/ OOzie. It will create a execution request for the execution engine while
it submits the job into the execution engine
a) Suggest renaming SubmissionEngine to a JobSubmissionManager.
b) SubmissionRequest is a JobRunRequest. See the java doc on the current code
SubmissionRequest, it should already hint us that this object holds the job
context to aid the execution engine
c) Change the apis in Execution Engine/ SubmissionManager to reflect the same,
i.e rename prepareSubmissionRequest to prepareExecutionRequest
d) The Submission term is overloaded in the code base. In one case it is used
to represent the JobRuns( history of the jobs) and in another place it is the
submission engine such as JobTracker/YARN/ OOzie. The act of submitting creates
a submission record. So submission is an artifact of completing//failing a
submit request. Prior to that it is still a job request.
YARN is an example of a submission engine and it can do much more than
submissions, so at some point we should revisit and outline what the
responsibilities of the submission engine API should be,
e) define other responsibilities of the submission engine. For instance, if we
are to add more monitoring/ tracking into how the job execution is progressing,
we should be able to add those apis to this entity. There is more room for
improvement for this api
3. Lastly add unit test for the JobManager!
