Subject [jira] [Commented] (FALCON-1555) succeeded-post-processing action fails in Oozie uber mode
Date Fri, 23 Oct 2015 11:27:27 GMT

    [ https://issues.apache.org/jira/browse/FALCON-1555?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14970849#comment-14970849

Pallavi Rao commented on FALCON-1555:

Oozie uber mode leverages Hadoop 2's uber mode for Launcher jobs. For Java actions, the Java
program is run within the launcher itself. In such cases, the FileSystem instance is shared
(from cache), an fs.close() results in errors during JOB_COMMIT. The general recommendation
is to not use fs.close() in user programs. Alternately, you can disable caching in the Hadoop
configuration, which might not be a good idea.
