Subject [jira] [Commented] (MAPREDUCE-4346) Adding a refined version of JobTracker.getAllJobs() and exposing through the JobClient
Date Tue, 26 Jun 2012 03:28:45 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4346?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13401142#comment-13401142
] 

Alejandro Abdelnur commented on MAPREDUCE-4346:
-----------------------------------------------

It looks good, I just wonder why the retired flag overrides the status filter, wouldn't make
sense to still respect the status filter and if you want all jobs just use an 'all' status
filter?

> The current implementation for JobTracker.getAllJobs() returns all submitted jobs in
any state, in addition to retired jobs. This list can be long and represents an unneeded overhead
especially in the case of clients only interested in jobs in specific state(s). 
> It is beneficial to include a refined version where only jobs having specific statuses
are returned and retired jobs are optional to include. 
> I'll be uploading an initial patch momentarily.
