Summary: MoveProcedure can be subtask of
ModifyTableProcedure/ReopenTableRegionsProcedure; ensure all kosher.
Key: HBASE-20682
URL: https://issues.apache.org/jira/browse/HBASE-20682
Project: HBase
Issue Type: Sub-task
Components: amv2
Reporter: stack
Assignee: stack
MoveProcedure is used in at least two places as a means of 'reopening' a region
after a config has changed. This issue is about review of MP so this usage is
first-class (and that MP is good procedure citizen running as a subprocedure.
In question is what should happen if the source server or the target servers
are offline when we go to run. As of the parent issue, we'll skip to the end.
Should we instead go ahead with the move (internally, if we are asked to assign
to an offline server, we'll pick another -- do same for unassign? Would help in
this reopen use case).
