Ahmed Radwan created MAPREDUCE-6215:
---------------------------------------
Summary: 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
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.
