示例1: deleteSnapshot

import org.apache.hadoop.hbase.master.MasterCoprocessorHost; //导入方法依赖的package包/类
/**
 * Delete the specified snapshot
 * @param snapshot
 * @throws SnapshotDoesNotExistException If the specified snapshot does not exist.
 * @throws IOException For filesystem IOExceptions
 */
public void deleteSnapshot(SnapshotDescription snapshot) throws SnapshotDoesNotExistException, IOException {
  // check to see if it is completed
  if (!isSnapshotCompleted(snapshot)) {
    throw new SnapshotDoesNotExistException(snapshot);
  }

  String snapshotName = snapshot.getName();
  // first create the snapshot description and check to see if it exists
  FileSystem fs = master.getMasterFileSystem().getFileSystem();
  Path snapshotDir = SnapshotDescriptionUtils.getCompletedSnapshotDir(snapshotName, rootDir);
  // Get snapshot info from file system. The one passed as parameter is a "fake" snapshotInfo with
  // just the "name" and it does not contains the "real" snapshot information
  snapshot = SnapshotDescriptionUtils.readSnapshotInfo(fs, snapshotDir);

  // call coproc pre hook
  MasterCoprocessorHost cpHost = master.getMasterCoprocessorHost();
  if (cpHost != null) {
    cpHost.preDeleteSnapshot(snapshot);
  }

  LOG.debug("Deleting snapshot: " + snapshotName);
  // delete the existing snapshot

  }

  // call coproc post hook
