Christopher Tubbs updated ACCUMULO-925:
---------------------------------------
Fix Version/s: (was: 1.6.0)
> Launch scripts should use a PIDfile
> -----------------------------------
>
> Key: ACCUMULO-925
> URL: https://issues.apache.org/jira/browse/ACCUMULO-925
> Project: Accumulo
> Issue Type: Improvement
> Components: scripts
> Reporter: Christopher Tubbs
> Assignee: Christopher Tubbs
>
> Start scripts should create PIDfiles to store the PID of running processes in
> a well known location (example: /var/run/accumulo/tserver.pid or
> $ACCUMULO_HOME/tserver.pid), for the following benefits:
> # Identify running services on a machine without executing and parsing the
> system process list, so stop scripts can kill them when they are unresponsive.
> # Prevent multiple instances of the same application from starting up (an
> environment variable for the location of the PIDfile can be used to allow
> multiple instances if it is desirable to do so).
> # Potentially provide an alternate mechanism for terminating a process by
> deleting its PIDfile rather than its lock in Zookeeper.
