Subject [jira] [Commented] (ACCUMULO-2554) MiniCluster Tests fail due to zookeeper
Date Thu, 17 Apr 2014 03:00:19 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13972249#comment-13972249
] 

Mike Drob commented on ACCUMULO-2554:
-------------------------------------

These failures happen approximately 50% of the time on our Jenkins.

I have two ideas for how we can resolve this, but both seem a little heavy-handed.
# We could switch from starting a full separate ZK to using an embedded one in the process.
There are [several ways to do this|http://stackoverflow.com/questions/9286054/is-it-possible-to-start-a-zookeeper-server-instance-in-process-say-for-unit-tes],
some of which would require us to bump up our dependency from 3.3 to 3.4
# We could provide configuration options to allow for using an existing ZK.

Assuming that nobody figures out what this error actually is, I'd prefer the first solution
but can see the merits of both.
