Description

TestJobOutputCommitter fails in a "ant test" run with following exception :

Output directory /home/amarsri/mapred/build/test/data/test-job-cleanup/output-2 already exists
org.apache.hadoop.fs.FileAlreadyExistsException: Output directory /home/amarsri/mapred/build/test/data/test-job-cleanup/output-2 already exists

But it passes when it is run individually.
