Description

For some reason that I do not have much idea, if input of a map/reduce job is gzipped, an unexpected null pointer may be returned from UTF8ByteArrayUtils.readline in the next method of StreamLineRecordReader. However the pointer is read before a null pointer check is performed. Thus a NPE may be thrown and fail the job.
