Subject [jira] [Updated] (HBASE-9338) Test Big Linked List fails on Hadoop 2.1.0

Elliott Clark updated HBASE-9338:
---------------------------------

    Attachment: HBASE-HBASE-9338-TESTING.patch

Here's a patch with some test changes I have been using to try and debug this issue.

Last night I ran a run with restart only chaos monkey.  That passed.

Then after that I tried to run slow deterministic with no merge region.  That Failed because
of an assignment manager issue.  There were 100 regions that were RIT for 4 hours. (I've seen
this before and its something we should look at but probably not a release blocker).

Then this morning I started another slow deterministic with no merge and that failed.  So
this leads me to believe that the data loss has something to do with two different actions
occurring at the the same time.  It also seems to suggest that region merge isn't the issue.
