> Provide test script to do rolling restart of RSs, master and do verification
> ----------------------------------------------------------------------------

> Key: HBASE-4442
> URL: https://issues.apache.org/jira/browse/HBASE-4442
> Project: HBase
> Issue Type: Improvement
> Components: test
> Reporter: Ming Ma
>
> We use a script that restart RS on a rolling fashion and found couple new
> issues in HBase in the area of server shutdown and region assignments.
> Running such test on a cluster will help to verify changes made in the area
> of server shutdown and regions assignment. The script could do the followings:
> 1. Based on the cluster config file, get the list of RSs and master server.
> 2. Restart RSs and Master periodically. The parameters like the sleep time
> between stop and start, the percentage of machines down at at given time,
> etc. should be configurable.
> 3. Use hbck or other ways to verify the cluster is moving. There will be
> inconsistency at a given time when you have lots of regions in transition. So
> that is ok. Script should mark test failure only when things aren't moving,
> for example, .META. isn't online for > timeoutmonitor period.
