Add facility to track currently progressing actions/workflows
-------------------------------------------------------------
Key: HBASE-3836
URL: https://issues.apache.org/jira/browse/HBASE-3836
Project: HBase
Issue Type: New Feature
Components: master, regionserver
Affects Versions: 0.92.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Fix For: 0.92.0
A lot of troubleshooting involves answering the question "well, what is your
server doing right now?" Today, that involves some combination of interpreting
jstack output and/or trudging through logs. Problems with these methods are:
(a) users may not have direct ssh access to regionserver machines in production
environments, (b) logs are very verbose, so hard to separate what's still going
on vs stuff that might have completed, and (c) interpreting jstack requires a
pretty good knowledge of the codebase plus diving into source code.
I'd like to add a singleton (for now) which takes care of tracking any major
actions going on in the region server and master.
