Unexpected NPE from the next method of StreamLineRecordReader fails map/reduce
jobs
-----------------------------------------------------------------------------------
Key: HADOOP-695
URL: http://issues.apache.org/jira/browse/HADOOP-695
Project: Hadoop
Issue Type: Bug
Components: contrib/streaming
Affects Versions: 0.8.0
Reporter: Hairong Kuang
Assigned To: Hairong Kuang
Fix For: 0.8.1
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.
