[jira] [Commented] (HIVE-13788) hive msck listpartitions need to make use of directSQL instead of datanucleus

    [ https://issues.apache.org/jira/browse/HIVE-13788?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15922714#comment-15922714 ] 

Sergey Shelukhin commented on HIVE-13788:
-----------------------------------------

Hmm... it would be better to expand directsql to existing getPartitions calls instead of using pruner w/o any expression to prune.
