Subject [jira] [Commented] (HIVE-10255) Parquet PPD support TIMESTAMP
Date Thu, 07 May 2015 16:02:59 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14532912#comment-14532912
] 

Dong Chen commented on HIVE-10255:
----------------------------------

In original patch, TimeStamp maps to Binary in Parquet. Related predicate cannot filter not-matched
row groups correctly. This is because the result of comparing Binary does not equal the result
of comparing Timestamp value.

Patch V1 use the new mapping in HIVE-10642, in which Timestamp is mapped to Long.
Local test passed, with the patch of HIVE-10642 and PARQUET-247.
