[jira] [Commented] (PHOENIX-5779) SplitSystemCatalogIT tests fail
with Multiple Regions error
[ https://issues.apache.org/jira/browse/PHOENIX-5779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17146275#comment-17146275 ]
Richard Antal commented on PHOENIX-5779:
----------------------------------------
I have added some extra logging and found out the old code created a _Deque_ for the _availableRegionServers_ and moved a region to a region server by calling _availableRegionServers.pop()_.
It failed sometimes because an HBase balance Chore run and moved a region to a region server that was in availableRegionServers Deque.
Instead of populating the availableRegionServers at the beginning of the function I suppose to check the available region servers right before the move.
