Karthik Kambatla commented on MAPREDUCE-6215:
---------------------------------------------
The patch looks benign. Mind adding a test case?
> Map is not cleared in SortedMapWritable.readFields(DataInput in)

> Key: MAPREDUCE-6215
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6215
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv1, mrv2
> Affects Versions: trunk
> Reporter: Ahmed Radwan
> Assignee: Ahmed Radwan
> Attachments: apache-sortedMapWritable.patch
>
>
> The readFields(DataInput in) in SortedMapWritable doesn't reset the
> internally used SortedMap. If this Writable object is reused then entries
> will get accumulated in the map with every call of readFields().
> I have seen this behavior when using SequenceFileInputFormat. See
> SequenceFileRecordReader.java and SequenceFile.Reader.
