Subject [jira] [Created] (MAPREDUCE-4273) Make CombineFileInputFormat split result JDK independent
Date Sun, 20 May 2012 05:18:41 GMT
Luke Lu created MAPREDUCE-4273:

             Summary: Make CombineFileInputFormat split result JDK independent
                 Key: MAPREDUCE-4273
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4273
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client
    Affects Versions: 1.0.3
            Reporter: Luke Lu
            Assignee: Luke Lu

The split result of CombineFileInputFormat depends on the iteration order of  nodeToBlocks
and rackToBlocks hash maps, which makes the result HashMap implementation hence JDK dependent.

This is manifested as TestCombineFileInputFormat failures on alternative JDKs.
