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
Assignee: Michael Weng
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 are moving, for
example, .META. isn't online for > timeoutmonitor period.
