> As we make jmx over http call to get information for HDFS/HBASE/MAPREDUCE, if their master daemons are down, we should show the down status correctly instead of showing broken UI or garbage information. It would take some time to have alert triggered for these master processes, so mean time dashboard front page if shows broken/garbage data, then user would not know the reason.
