Subject [jira] [Commented] (HIVE-19629) Enable Decimal64 reader after orc version upgrade
Date Sun, 17 Jun 2018 18:21:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-19629?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16515177#comment-16515177

Prasanth Jayachandran commented on HIVE-19629:
----------------------------------------------

branch-3 has several existing failures (refer HIVE-19881, HIVE-19739). The branch-3 failures
are same as the ones in HIVE-19881 and HIVE-19739. I am not sure the test changes that went
in for master also went into branch-3 that could have solved the branch-3 test issues (timeout
changes, tmp directory changes, retry changes).
