public static void configureJob(org.apache.hadoop.conf.Configuration conf,
                String snapshotName,
                org.apache.hadoop.fs.Path restoreDir)
                         throws IOException

Configures conf for the snapshot job. Call only when assertSupportsTableSnapshots() returns true.

Throws:

IOException

createTableSnapshotRegionSplit

public static org.apache.hadoop.mapred.InputSplit createTableSnapshotRegionSplit()

Create a bare TableSnapshotRegionSplit. Needed because Writables require a default-constructed instance to hydrate from the DataInput. TODO: remove once HBASE-11555 is fixed.
