[jira] [Commented] (HIVE-3397) PartitionPruner should log why it is not pushing the filter down to JDO

    [ https://issues.apache.org/jira/browse/HIVE-3397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13437605#comment-13437605 ] 

Carl Steinbach commented on HIVE-3397:
--------------------------------------

PartitionPruner.prune() falls back to doing a sequential scan of all partitions if the filter expression can't be pushed down to JDO. When this happens it should log a message explaining why it was unable to push the filter down to JDO.
