> Information about "setupProgress" and "cleanupProgress" are not available after a job
completion. These properties are ignored during creating JobReport since they were not added
to jhist file.
> We can get this information during a job is running:
> {code}
> import org.apache.hadoop.mapred.JobClient
> import org.apache.hadoop.conf.Configuration
> val client = new JobClient(new Configuration())
> val job = client.getJob("job_1535984902382_0006")
> val setup = job.setupProgress()
> {code}
> When job runnin:
> {code}
> scala> val setup = job.setupProgress()
> setup: Float = 1.0
> {code}
> When job already finished:
> {code}
> scala> val setup = job.setupProgress()
> setup: Float = 0.0
> {code}
> JobReport interface includes getCleanupProgress and getSetupProgress methods. But these
methods ignore during creating JobReport in CompletedJob#constructJobReport(). setupProgress
and cleanupProgress properties set in JobImpl class but JobFinishedEvent and JobUnsuccessfulCompletionEvent
do not include this information. As the result, these properties do not include in jhist file.
> We can add these properties to jhist file but of course, this is the incompatible change.
These changes should be applied for a major release.
