Examples of org.apache.hadoop.hbase.YouAreDeadException

org.apache.hadoop.hbase.YouAreDeadException
This exception is thrown by the master when a region server reports and is already being processed as dead. This can happen when a region server loses its session but didn't figure it yet.

      // host name, port and start code all match with existing one of the
      // dead servers. So, this server must be dead.
      String message = "Server " + what + " rejected; currently processing " +
          serverName + " as dead server";
      LOG.debug(message);
      throw new YouAreDeadException(message);
    }
    // remove dead server with same hostname and port of newly checking in rs after master
    // initialization.See HBASE-5916 for more information.
    if ((this.services == null || ((HMaster) this.services).isInitialized())
        && this.deadservers.cleanPreviousInstance(serverName)) {
