> Currently, whenever fetch of a map output fails the corresponding MapOutputLocation is
added to a List datastructure for later retrial. But, if the failure was due to a lost task,
the entry that was added is not deleted. For such cases, unnecessary retrials will happen.
This situation should be prevented.
