[jira] [Commented] (HBASE-8803) region_mover.rb should move multiple regions at a time

["Jean-Marc Spaggiari (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-8803?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13692999#comment-13692999 ] 

Jean-Marc Spaggiari commented on HBASE-8803:
--------------------------------------------

Also, today region_mover assigns the regions randomly. Should we go round-robbin instead?

Working on a fix for 0.94. Will most probably do the job for trunk too. More to come.

> When there is many regions in a cluster, rolling_restart can take hours because region_mover is moving the regions one by one.
