[jira] [Created] (HBASE-9696) Master recovery ignored online merge znode

Jimmy Xiang created HBASE-9696:
----------------------------------

             Summary: Master recovery ignored online merge znode
                 Key: HBASE-9696
                 URL: https://issues.apache.org/jira/browse/HBASE-9696
             Project: HBase
          Issue Type: Bug
          Components: master, Region Assignment
            Reporter: Jimmy Xiang
            Assignee: Jimmy Xiang


The online merge znode uses the new region to be created.  When master restarts, the new region is still unknown if the merging is not completed. Therefore the znode is ignored, which should not.  That means the two merging regions could be moved around.  This could cause some data loss if we are not luck.
