Suresh Srinivas commented on HDFS-2083:
---------------------------------------

Minor comments:
# "Namenode over to get attributed" - over what? It would be good add some description that
this connects over http to get Namenode JMX attributes.
# Decommissionnode -> DecommissionNode (at many places)

> HADOOP-7144 added JMXJsonServlet into Common.  It gives the capability to query statistics
and metrics exposed via JMX to be queried through HTTP.  We adopt this into HDFS.  This provides
the alternative solution to HDFS-1874.
