Subject [jira] [Commented] (MAPREDUCE-5870) Support for passing Job priority through Application Submission Context in Mapreduce Side
Date Sat, 21 Nov 2015 09:31:11 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5870?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15020354#comment-15020354

Sunil G commented on MAPREDUCE-5870:

Findbugs warnings are unrelated. Few javac warnings are populated due to deprecation which
is not introduced by this one. I will check why this happened.
DistributedCache in org.apache.hadoop.mapreduce.filecache has been deprecated
I will file a ticket for {{TestMRAppMaster.testMRAppMasterMidLock}} failure.

> Job Priority support in MapReduce.
> 1. Job Priority can be set from client side as below (Configuration and api).
> 			- JobConf.getJobPriority() and JobConf.setJobPriority(JobPriority priority) 
> 			- We can also use configuration "mapreduce.job.priority".
> 		Now this Job priority can be passed in Application Submission context from Client side.
> 		Here we can reuse the MRJobConfig.PRIORITY configuration. 
> 2. CLI changes to support {{--set-priority}}. Run time change of JobPriority is also
to be handled.
> 3. Change {{Job}} to have the support for {{setPriority}} and {{getPriority}} (getter
is handled with JobStatus)
