Matteo Bertozzi created HBASE-14128:
---------------------------------------

             Summary: Fix inability to run Multiple MR over the same Snapshot
                 Key: HBASE-14128
                 URL: https://issues.apache.org/jira/browse/HBASE-14128
             Project: HBase
          Issue Type: Bug
          Components: mapreduce, snapshots
            Reporter: Matteo Bertozzi
            Priority: Minor


from the list, running multiple MR over the same snapshot does not work
{code}
public static void copySnapshotForScanner(Configuration conf, FileSystem ..
    RestoreSnapshotHelper helper = new RestoreSnapshotHelper(conf, fs,
      manifest, manifest.getTableDescriptor(), restoreDir, monitor, status);
{code}
the problem is that manifest.getTableDescriptor() will try to clone the snapshot with the
same target name. ending up in "file already exist" exceptions.
we just need to clone that descriptor and generate a new target table name
