Blacklisting of TaskTrackers should take into account the user-ID
-----------------------------------------------------------------
Key: HADOOP-4808
URL: https://issues.apache.org/jira/browse/HADOOP-4808
Project: Hadoop Core
Issue Type: Improvement
Components: mapred
Affects Versions: 0.20.0
Reporter: Devaraj Das
With HADOOP-4305, it is possible to blacklist TaskTrackers across jobs. It
might make sense to also take into account the users whose tasks are being run
on the TaskTrackers, and use it in the blacklisting strategy.
