Vinod K V updated HADOOP-5570:
------------------------------
Attachment: HADOOP-5570-20090614.txt
Attaching a patch to fix the issue. This patch reads /proc/pid/cmdline to get
the command line of each process and uses this to get the process-tree's dump.
The dump is logged both on the TaskTracker and is displayed on the web-ui in
the Errors tab. Added a simple test-case and also tested this on a local
cluster.
> TaskMemoryManager should log process-tree's status while killing tasks.
