Description

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);
