----------------------------

             Summary: TestReplicationQueueFailover* runs for a minute, spews 3/4million lines
complaining 'Filesystem closed', has an NPE, and still passes?
                 Key: HBASE-7982
                 URL: https://issues.apache.org/jira/browse/HBASE-7982
             Project: HBase
          Issue Type: Bug
            Reporter: stack
            Priority: Blocker


I was trying to look at why the odd time Hudson OOMEs trying to make a report on 0.95 build
#4 https://builds.apache.org/job/hbase-0.95/4/console:

{code}

We are trying to allocate a big buffer and failing.

Looking at reports being generated, we have quite a few that are > 10MB in size:

... with TestReplicationQueueFailover* being order of magnitude bigger than the others.

Looking in the test I see both spewing between 800 and 900 thousand lines in about a minute.
 Here is their fixation:

These tests are 'succeeding'?

I also see in both:
