Subject [jira] [Commented] (HIVE-12364) Distcp job fails when run under Tez
Date Tue, 08 Dec 2015 22:19:10 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12364?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15047580#comment-15047580
] 

Mithun Radhakrishnan commented on HIVE-12364:
---------------------------------------------

Hey, [~prasanth_j]. I'd be keen on knowing what other patches this might need. Were these
also critical bug-fixes?

This patch seems pretty self-contained. It's the result of Hive's own InputFormats implementing
old-api, while DistCp uses the new MR apis. We ran into this problem today. I also ran into
a similar problem when introducing a custom MR job for something else I'm working on. (That
I'll explain in another JIRA.)
