It also includes a unit test to show the problem. > 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 > Labels: test > Fix For: 0.7, 0.8 > > Attachments: MAHOUT-1284.patch > > Original Estimate: 1h > Remaining Estimate: 1h > > 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. -- This message is automatically generated by JIRA.
