--------------------------------------------------------------

Plz check the new patch [https://issues.apache.org/jira/secure/attachment/12371797/HADOOP-2419.patch].
Earlier the  calls to {{MapTask.Collect()}} were not thread-safe. Now the call to {{Collect()}}
is made thread-safe. Let us know if this patch works fine.
