Region lost (disabled) when -ROOT- offline
------------------------------------------
Key: HBASE-1742
URL: https://issues.apache.org/jira/browse/HBASE-1742
Project: Hadoop HBase
Issue Type: Bug
Reporter: stack
I killed server with -ROOT-. It came back eventually but meantime we'd asked a
server to open a region. It failed in the below but then we never try to open
the region elsewhere.
