Date Sat, 31 Mar 2012 18:54:25 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4083?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amar Kamat updated MAPREDUCE-4083:
----------------------------------

    Attachment: mapreduce-4083-v1.0.patch

Attaching a patch that fixes this issue. With this patch, the emulators will return progress
= 1 when the plugin is disabled indicating that no emulation is required. Added a JUnit test
for the same.

test-patch and ant tests passed on my box.
