Missing rows after medium intensity insert
------------------------------------------

                 Key: HBASE-1784
                 URL: https://issues.apache.org/jira/browse/HBASE-1784
             Project: Hadoop HBase
          Issue Type: Bug
    Affects Versions: 0.20.0
            Reporter: Jean-Daniel Cryans
            Priority: Blocker


This bug was uncovered by Mathias in his mail "Issue on data load with 
0.20.0-rc2". Basically, somehow, after a medium intensity insert a lot of rows 
goes missing. Easy way to reproduce : PE. Doing a PE scan or randomRead 
afterwards won't uncover anything since it doesn't bother about null rows. 
Simply do a count in the shell, easy to test (I changed my scanner caching in 
the shell to do it faster).

I tested some light insertions with force flush/compact/split in the shell and 
it doesn't break.
