      Description

      Currently the JMX beans returns much of the data contained on the HDFS Health webpage (dfsHealth.html). However there are several other attributes that are required to be added, that can only be accessed from within NameNode.

      For this reason a new JMX bean is required (NameNodeStatusMXBean) which will expose the following attributes in NameNode:
      Role
      State
      HostAndPort

      also a list of the corruptedFiles should be exposed by NameNodeMXBean.
