             Summary: Solve the problem that the inspection period of HeartbeatManager#Monitor can be configured
                 Key: HDFS-15941
                 URL: https://issues.apache.org/jira/browse/HDFS-15941
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: JiangHua Zhu


Now when HeartbeatManager#Monitor checks whether the datanode is healthy, it does an action every 5 seconds. We should set up configurable.
Monitor#run()  {
 ......
       try {
          Thread.sleep(5000);  // 5 seconds
        } catch (InterruptedException ignored) {
        }
......
}
