Subject [jira] [Created] (ACCUMULO-4012) FATE lock-up
Date Tue, 29 Sep 2015 15:46:04 GMT
Eric Newton created ACCUMULO-4012:
-------------------------------------

             Summary: FATE lock-up
                 Key: ACCUMULO-4012
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4012
             Project: Accumulo
          Issue Type: Bug
          Components: master, tserver
    Affects Versions: 1.6.3
         Environment: large production cluster
            Reporter: Eric Newton
            Assignee: Eric Newton


On a large production cluster, some periodic data processing hangs on FATE transactions. The
basic operation is to bulk load the results of a map-reduce job into a temporary table, which
is then later deleted. Increasing the number of FATE threads has not improved the situation.

The details are not clear, and unfortunately this system is not online, so I cannot reproduce
the logs easily, but they would be huge anyhow.
