Andrew Purtell resolved HBASE-4442. ----------------------------------- Resolution: Incomplete Assignee: (was: Michael Weng) > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
