Subject [jira] Created: (HBASE-1742) Region lost (disabled) when -ROOT- offline
Date Tue, 04 Aug 2009 03:45:14 GMT
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.
