I have tried implementing #1 on web UI of NameNode, Router, and DataNode.
After applying `HDFS-14928.001.patch`, the WebUI will look like the followings:
!HDFS-14928.jpg|width=600!
During the implementation, I came across two issues that I want to discuss:
# I haven't modify the Web UI of DataNode because JMX of DN does not contain
any information about its own running status.
We have to either A) expose the DN's running status in JMX metrics or B) use
ajax to query the JMX of NN. We can also C) skip the changes for now.
Which do you think is better amoug A,B or C?
# NNs can be in Safemode and Standby at the same time. In current
implementation, safemode will never be shown on Overview page.
Should we change it so that when a Standby NN is in Safemode, we show Safemode
icon.
