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.
