>             Project: Hadoop HDFS

>          Components: namenode
>    Affects Versions: 3.0.0, 2.1.0-beta, 2.0.4-alpha
>            Reporter: Trevor Lorimer
>            Assignee: Trevor Lorimer
>             Fix For: 3.0.0, 2.3.0
>         Attachments: HDFS-5004.diff, HDFS-5004.diff, HDFS-5004.diff
> 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.
