Prasanth J updated HIVE-7067: ----------------------------- Status: Patch Available (was: Open) > Min() and Max() on Timestamp and Date columns for ORC returns wrong results > --------------------------------------------------------------------------- > > Key: HIVE-7067 > URL: https://issues.apache.org/jira/browse/HIVE-7067 > Project: Hive > Issue Type: Bug > Reporter: Prasanth J > Assignee: Prasanth J > Attachments: HIVE-7067.1.patch > > > min() and max() of timestamp and date columns of ORC table returns wrong > results. The reason for that is when ORC creates object inspectors for date > and timestamp it uses JAVA primitive objects as opposed to WRITABLE objects. > When get() is performed on java primitive objects, a reference to the > underlying object is returned whereas when get() is performed on writable > objects, a copy of the underlying object is returned. > Fix is to change the object inspector creation to return writable objects for > timestamp and date. -- This message was sent by Atlassian JIRA (v6.2#6252)
