public static org.apache.hadoop.fs.Path getRegionSnapshotDirectory(HBaseProtos.SnapshotDescription desc,
org.apache.hadoop.fs.Path rootDir,
String regionName)
Under the per-snapshot directory, specific files per-region are kept in a similar layout as per the current directory layout.
desc - description of the snapshotrootDir - root directory for the hbase installationregionName - encoded name of the region (see HRegionInfo.encodeRegionName(byte[]))

org.apache.hadoop.fs.Path snapshotRegionDir,
org.apache.hadoop.fs.FileStatus[] families)
snapshot - description of the snapshot being takesnapshotRegionDir - directory in the snapshot where the region directory information
should be storedfamilies - families to be added (can be null)
public static TimeoutExceptionInjector getMasterTimerAndBindToMonitor(HBaseProtos.SnapshotDescription snapshot,
org.apache.hadoop.conf.Configuration conf,
ForeignExceptionListener monitor)
snapshot - snapshot to monitorconf - configuration to use when getting the max snapshot lifemonitor - monitor to notify when the snapshot life expires
