> 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);
