----------------------------------
Summary: Move operations of RSGroup should allow retry and correct
region assignments
Key: HBASE-22642
URL: https://issues.apache.org/jira/browse/HBASE-22642
Project: HBase
Issue Type: Bug
Components: rsgroup
Reporter: Xiaolin Ha
Assignee: Xiaolin Ha
Currently, when moving tables or servers to a group, only groupInfo is checked.
And in RSGroup implementation, groupinfo is written to disk before regions
movements are done. If there are some problems caused move regions abort, some
regions will be on wrong regionservers. What's the worse, retry the move
operation will be rejected because of the correct groupinfo.
We think when moving, not only groupInfo should be checked, but also relevant
region assignments should be checked and corrected.
