Hemanth Yamijala commented on HADOOP-2947:
------------------------------------------
After looking at the changes, we realize there are some issues with the patch.
Also, this is requiring changes to a core functionality of HOD. So, moving this
out of the 0.17 list.
> [HOD] Hod should redirect stderr and stdout of Hadoop daemons to assist
> debugging

> Copied from internal bug details from Koji:
> ==========================
> Sometimes JobTracker/TaskTracker starts consuming 99% cpu and stops
> responding to 'jstack' call. In those cases,
> usually it still responds to kill -QUIT signal which forces the jvm to dump
> the stack to stdout.
> Please have the stdout of JT/TT redirected to a file.
> Adding stderr.
> If thread has an uncaught exception, it prints out to stderr and dies.
> ==========================
