time lag between job completion and job beng avail in JH server makes Oozie fail
--------------------------------------------------------------------------------
Key: MAPREDUCE-4033
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4033
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.3
Reporter: Alejandro Abdelnur
Priority: Critical
Fix For: 0.23.3
Oozie testcases are failing randomly because MR2 reports the job as unknown.
This seems to happen when Oozie queries via JobClient.getJob(<JOBID>) for a
<JOBID> that just finished.
{code}
org.apache.oozie.action.ActionExecutorException: JA017: Unknown hadoop job
[job_1332176678205_0011] associated with action
[0000000-120319101023910-oozie-tucu-W@pig-action]. Failing this action!
{code}
Oozie reports this error when JobClient.getJob(<JOBID>) returns NULL.
Looking at the mini cluster logs the job definitely run.

It seems there is a gap until the the job is avail in the JH server.
If this gap is unavoidable we need to ensure Oozie always waits at least the
gap time before querying for a job.
