Hemanth Yamijala updated HADOOP-5022:
-------------------------------------
Release Note: Implemented an option, retain-master-logs, in logcondense
support script that would indicate whether the script should delete hadoop
master logs as part of its cleanup process. By default this option is false,
that makes the change incompatible with earlier versions of logcondense.
Hadoop Flags: [Incompatible change, Reviewed] (was: [Reviewed,
Incompatible change])
> [HOD] logcondense should delete all hod logs for a user, including jobtracker
> logs

> Currently, logcondense.py does not delete jobtracker logs that it uploads to
> the DFS when the HOD cluster is deallocated. This will result in the hod-logs
> directory to slowly accumulate a whole bunch of jobtracker logs. Particularly
> for users who run a lot of user jobs, this could fill up the namespace.
> Further these directories will cause the logcondense program to keep
> repeatedly looking at these directories stressing out the namenode. So,
> logcondense.py should optionally also delete the jobtracker logs.
