> The framework map/reduce bridge methods make a check at the beginning of the respective methods whether _MROutputThread_ encountered an exception while writing keys/values that the streaming process emitted. However, if the exception happens in _MROutputThread_ after the last call to the map/reduce method, the exception goes undetected. An example of such an exception is an exception from the _DFSClient_ that fails to write to a file on the HDFS.
