[jira] Created: (MAPREDUCE-1178) MultipleInputs fails with
ClassCastException
MultipleInputs fails with ClassCastException
---------------------------------------------
Key: MAPREDUCE-1178
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1178
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.21.0
Reporter: Jay Booth
Priority: Blocker
Fix For: 0.21.0
Attachments: MAPREDUCE-1178.patch
When running MultipleInputs against the new API, we get failures with this ClassCastException:
java.lang.ClassCastException: org.apache.hadoop.mapreduce.lib.input.TaggedInputSplit cannot be cast to org.apache.hadoop.mapreduce.lib.input.FileSplit
at org.apache.hadoop.mapreduce.lib.input.LineRecordReader.initialize(LineRecordReader.java:70)
at org.apache.hadoop.mapreduce.lib.input.KeyValueLineRecordReader.initialize(KeyValueLineRecordReader.java:59)
at org.apache.hadoop.mapred.MapTask$NewTrackingRecordReader.initialize(MapTask.java:439)
at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:599)
at org.apache.hadoop.mapred.MapTask.run(MapTask.java:323)
at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:257)
The unit test for MultipleInputs doesn't actually run a job so this snuck through while still passing the unit test. Attached patch fixes the unit test to expose the failure and does a little casting kung-fu in LineRecordReader to avoid the error.
