             Summary: An Offline SplitParent Region can be assigned breaking split references
                 Key: HBASE-9204
                 URL: https://issues.apache.org/jira/browse/HBASE-9204
             Project: HBase
          Issue Type: Bug
          Components: Region Assignment
    Affects Versions: 0.94.10, 0.95.1, 0.98.0
            Reporter: Matteo Bertozzi
            Priority: Blocker


An offline split parent region can be assigned by using 'assign' from shell.

This may trigger a compaction on the split parent region that should be offline, breaking the references of the two daughters.

The easy way to test this is:
 * disable compactions
 * create a table and insert some row
 * split
 * shutdown the master (otherwise there's a state checked inside the AssignmentManager)
 * start the master
 * assign the region marked as OFFLINE => true, SPLIT => true (the compaction on region startup will probably break the reference of the two  daughters)
