Subject [jira] Created: (HADOOP-3630) CompositeRecordReader: key and values can be in uninitialized state if files being joined have no records

CompositeRecordReader: key and values can be in uninitialized state if files being joined have
no records
---------------------------------------------------------------------------------------------------------

                 Key: HADOOP-3630
                 URL: https://issues.apache.org/jira/browse/HADOOP-3630
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.17.0
            Reporter: Jingkei Ly


I am using org.apache.hadoop.mapred.join.CompositeInputFormat to do an outer-join across a
number of SequenceFiles. This works fine in most circumstances, but I get NullPointerExceptions/uninitialized
data (where Writable#readFields() has not been called) when some of the files being joined
have no records in them.
