Subject [jira] [Commented] (HIVE-6113) Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient
Date Thu, 19 Nov 2015 23:09:11 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6113?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15014691#comment-15014691
] 

Sergey Shelukhin commented on HIVE-6113:
----------------------------------------

Wrt the patch, it looks like all the tests have failed above.
Also given the code changes, I assume there's no way to downgrade to old DN jars on a running
Hive build if some issue is discovered? I love it when people change public APIs to beautify
some package name or whatever. Maybe we can try to find the classes by string name to be able
to use both jars?
