             Summary: TestFileOutputCommitter fails on Windows
                 Key: MAPREDUCE-7108
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7108
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 2.9.1, 3.1.0
            Reporter: Zuoming Zhang
             Fix For: 2.9.1, 3.1.0


TestFileOutputCommitter.java fails on Windows.

Reason:

This is because in testMapFileOutputCommitterInternal, after executing 
MapFileOutputFormat.getReaders(outDir, conf), the readers are not properly 
closed. So other apis that attempt to delete the existing file fails due to the 
file handler already being used.

 

Solution:

Close all readers after call MapFileOutputFormat.getReaders(outDir, conf);
