> Having configurable capability to overwrite the file with the same name
> already exists (Line no 90 in org.apache.orc.impl.PhysicalFsWriter).
> Use Case:
> I am using OrcOutputFormat with MultipleOutput in my MapReduce job.
> Since MultipleOutput does not uses OutputCommitter so there are half/corrupt
> files are left from the failed reducers.
> Here the files with the same name will be overwritten by the retry attempt
> and it will guarantee correct result from a successful job.
