Amar Kamat updated MAPREDUCE-430:
---------------------------------
Release Note: Various code paths in the framework caught Throwable and
tried to do inline cleanup. In case of OOM errors, such inline-cleanups can
result into hung jvms. With this fix, the TaskTracker provides a api to report
fatal errors (any throwable other than FSErrror and Exceptions). On catching a
Throwable, Mapper/Reducer tries to inform the TT.
> Task stuck in cleanup with OutOfMemoryErrors
