[jira] [Commented] (MAPREDUCE-397) In JobInProgress, failed TIP
should be added back to the non-running queue only if the tip has not
failed.

Review request for hadoop-mapreduce.
Summary
-------
In case of a task failure, the corresponding TIP is added back to the non-running list via failMap()/failReduce() api. This reentry should be done only for TIPs that have not failed. Reentry is useless for failed TIPs.
Change checks for tip.isFailed() before proceeding.
This addresses bug MAPREDUCE-397.
