Josh Elser created ACCUMULO-3442:
------------------------------------

             Summary: Occasional failure of BlockedIOStreamTest
                 Key: ACCUMULO-3442
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3442
             Project: Accumulo
          Issue Type: Bug
          Components: test
            Reporter: Josh Elser
            Priority: Minor
             Fix For: 1.6.3


I see this test fail every now and again (happened to me yesterday and now again today)

When I rerun the test, it passes on the second attempt. Not sure if there's some edge case
the test isn't covering correctly (since it use a Random object) or what. I'll try to log
other error conditions when I see it again.
