    Description

      HDFS might want to leverage health check functionality available in YARN in both namenode https://issues.apache.org/jira/browse/HDFS-7400 and datanode https://issues.apache.org/jira/browse/HDFS-7441.

      We can move health check functionality including the protocol between hadoop daemons and health check script to hadoop-common. That will simplify the development and maintenance for both hadoop source code and health check script.

      Thoughts?
