Subject [jira] [Commented] (HIVE-8646) Hive class loading failure when executing Hive action via oozie workflows
Date Fri, 31 Oct 2014 06:46:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-8646?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14191487#comment-14191487
] 

Gunther Hagleitner commented on HIVE-8646:
------------------------------------------

I think we should just go with Navis' patch for now. Since he removed the FieldSchema reference
there's a good chance this resolves the oozie issue. [~venkatnrangan] can test once it's in.
The problem with "it's just a boolean" is that we clone tasks a lot and there might be weird
side effects of removing the block. +1 for trunk and branch.

> When running Hive actions with Oozie we hit this issue sometimes.    What is interesting
is that we have all the necessary jars in the classpath (or atleast are expected to be localized).
> This static initialization block is introduced by HIVE-3925.
