Phabricator commented on HIVE-5047:
-----------------------------------

ashutoshc has requested changes to the revision "HIVE-5047 [jira] Hive client filters partitions
incorrectly via pushdown in certain cases involving "or"".

  Wondering whether we should go into the function only in cases when its AND ?

INLINE COMMENTS
  ql/src/java/org/apache/hadoop/hive/ql/optimizer/ppr/PartitionPruner.java:270 Isn't the better
fix following:
  -  if (udf instanceof GenericUDFOPAnd ||  udf instanceof GenericUDFOPOr )
  + if (udf instanceof GenericUDFOPAnd )
