[HOD] Hod should redirect stderr and stdout of Hadoop daemons to assist
debugging
---------------------------------------------------------------------------------
Key: HADOOP-2947
URL: https://issues.apache.org/jira/browse/HADOOP-2947
Project: Hadoop Core
Issue Type: Improvement
Components: contrib/hod
Affects Versions: 0.16.0
Reporter: Hemanth Yamijala
Fix For: 0.17.0
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.
