    Description

      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.
