[jira] [Reopened] (HBASE-7483) TestHRegionOnCluster and
TestSplitTransactionOnCluster are racy with HBaseAdmin.move()
[ https://issues.apache.org/jira/browse/HBASE-7483?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lars Hofhansl reopened HBASE-7483:
----------------------------------
Meh. This is still happening. I can't explain how, though. This exception happens when the assignment manager does not know about this region.
My previous patch checks whether the assignment manager does know this region, so it seems impossible now.
