hbase-daemon.sh should clean up PID files on process stop
---------------------------------------------------------
Key: HBASE-3430
URL: https://issues.apache.org/jira/browse/HBASE-3430
Project: HBase
Issue Type: Bug
Components: scripts
Reporter: Gary Helmling
Priority: Trivial
I just did a simple watchdog script for internal use to enable HBase process
restarts on failure. While most of it was easy, I found no way to distinguish
between a process failure and intentional stop, since the HBase scripts leave
PID files sitting around after shutdown.
I think it would be generally useful for hbase-daemon.sh to cleanup PID files
on successful process stop. This is really just a matter of adding "rm $pid"
after stop completes. Any concerns/objections?
