Subject [jira] [Commented] (HIVE-7202) DbTxnManager deadlocks in hcatalog.cli.TestSematicAnalysis.testAlterTblFFpart()
Date Thu, 19 Jun 2014 21:07:24 GMT

    [ https://issues.apache.org/jira/browse/HIVE-7202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14037885#comment-14037885
] 

Alan Gates commented on HIVE-7202:
----------------------------------

Tests pass when run locally except root_dir_external_table and authorization_ctas, both of
which also fail on trunk.  So I do not think these failures are related to the patch.
