---------------------------------
Summary: Serialization is missing in MockMultipleOutputs
Key: MRUNIT-198
URL: https://issues.apache.org/jira/browse/MRUNIT-198
Project: MRUnit
Issue Type: Bug
Affects Versions: 1.1.0
Reporter: Lars Grote
Fix For: 1.1.0
Hi,
with issue MRUNIT-13 MockMultipleOutputs was introduced. Which is great!
Unfortunately the inner class MockRecordWriter doesn't serialize the Object and
therefore isn't storing a copy of the Object but the Object itself. I would
suggest to use org.apache.hadoop.mrunit.internal.output.MockOutputCollector
instead of the inner class. This Collector does store a copy of the Object and
I see no point in having more or less the same Collector/Writer twice.
Another thing that bugs me, is that MockMultipleOutputs requires you to use
Comparable Objects in your MR Jobs, and I don't see for what reason this
restriction is imposed on me.
I'll provide a patch for this soon and would be glad if someone can comment on
it.
Cheers, Lars
