----------------------------------
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.
