---------------------------------------
Summary: DummyRecordWriter's bug with reused Writables
Key: MAHOUT-1284
URL: https://issues.apache.org/jira/browse/MAHOUT-1284
Project: Mahout
Issue Type: Bug
Affects Versions: 0.7, 0.8
Reporter: Maysam Yabandeh
Priority: Minor
Fix For: 0.8, 0.7
It is a recommended practice to reuse the Writable objects. DummyRecordWriter,
which is used for testing in Mahout, however keeps the same Writable instance
in a map: next time that the user reuses the Writable object, the internal map
of DummyRecordWriter changes as well. This makes DummyRecordWriter fail for
testing the MapReduce jobs that reuse the Writables.
