 * [PHOENIX-6273](https://issues.apache.org/jira/browse/PHOENIX-6273) | *Major* | **Add support to handle MR Snapshot restore externally**
 
 Adds mapreduce configuration param "phoenix.mapreduce.external.snapshot.restore" which when set to true indicates that snapshot-based MapReduce jobs shouldn't try to restore the snapshot themselves, but assume an external application has already done so.
