Minor nits: # I suppose the reason we are setting the message for HSFileException is to log it. However, the code doesn't log anything. We should do one of the two: ## Log before throwing HSFileException and don't set the message. ## Log when we catch HSFileException. # The test uses wildcard imports - let us avoid that. > Add capability to set JHS job cache to a task-based limit > - > > Key: MAPREDUCE-6622 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6622 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: jobhistoryserver >Affects Versions: 2.7.2 >Reporter: Ray Chiang >Assignee: Ray Chiang > Labels: supportability > Attachments: MAPREDUCE-6622.001.patch, MAPREDUCE-6622.002.patch, > MAPREDUCE-6622.003.patch, MAPREDUCE-6622.004.patch, MAPREDUCE-6622.005.patch, > MAPREDUCE-6622.006.patch, MAPREDUCE-6622.007.patch, MAPREDUCE-6622.008.patch, > MAPREDUCE-6622.009.patch, MAPREDUCE-6622.010.patch, MAPREDUCE-6622.011.patch, > MAPREDUCE-6622.012.patch > > > When setting the property mapreduce.jobhistory.loadedjobs.cache.size the jobs > can be of varying size.
