Jay Booth updated MAPREDUCE-1170:
---------------------------------
Attachment: MAPREDUCE-1170.patch
New patch fixes ClassCastException in LineRecordReader via
<pre>
if (split instanceof TaggedInputSplit) fileSplit = (FileSplit)
((TaggedInputSplit) split).getInputSplit();
else fileSplit = (FileSplit) split;
</pre>
The old test just added the inputs and verified they were added, didn't
actually run a job, so this error snuck through.
New test runs a job with MultipleInputs and 2 different mapper classes,
ensuring that output is correct. Passes.
The test fails on 0.21 branch though -- I'll make a separate JIRA and post a
patch for that as well
> MultipleInputs doesn't work with new API in 0.20 branch
