> HADOOP-15850 fixes a bug where CopyCommitter#concatFileChunks unconditionally tried to concatenate the files being DistCp'ed to target cluster (though the files are independent).
> Following is the log snippet of the failed concatenation attempt:

> Backup and Restore uses DistCp to transfer files between clusters.
> Without the fix from HADOOP-15850, the transfer would fail.
> This issue is to document the hadoop versions which contain HADOOP-15850 so that user of Backup and Restore feature knows which hadoop versions they can use.
