> need ops documentation that details supervision of ZK server processes
> ----------------------------------------------------------------------

> Key: ZOOKEEPER-485
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-485
> Project: Zookeeper
> Issue Type: Bug
> Components: documentation, server
> Reporter: Patrick Hunt
> Assignee: Patrick Hunt
> Fix For: 3.3.0
>
> Attachments: ZOOKEEPER-485.patch
>
>
> We need ops documentation detailing what to do if the ZK server VM fails - by
> fail I mean the jvm process
> exits/dies/crashes/etc...
> In general a supervisor process should be used to start/stop/restart/etc...
> the ZK server vm.
> Something like daemontools http://cr.yp.to/daemontools.html could be used, or
> more simply a wrapper script
> should monitor the status of the pid and restart if the jvm fails. It's up to
> the operator, if this is not done
> automatically then it will have to be done manually, by operator restarting
> the ZK server jvm
> The inherent behavior of ZK wrt to failures - ie that it automatically
> recovers as long as quorum is maintained -
> fits into this nicely.
