Subject [jira] [Commented] (HAMA-679) ZooKeeper is not shutdown gracefully in TestZooKeeper
Date Wed, 21 Nov 2012 18:51:58 GMT

    [ https://issues.apache.org/jira/browse/HAMA-679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13502196#comment-13502196
] 

Thomas Jungblut commented on HAMA-679:
--------------------------------------

That is no closing failure, it is because the ZK was started as embedded server which is not
supported.

I hope that this will be resolved by the update. Otherwise we have to provide the InMemoryDataTree
somehow.
