------------------------------
Summary: Document the hadoop versions using which backup and
restore feature works
Key: HBASE-21381
URL: https://issues.apache.org/jira/browse/HBASE-21381
Project: HBase
Issue Type: Task
Reporter: Ted Yu
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.
