Ravi Prakash commented on HDFS-12781:
-------------------------------------
Hi Brahma! Is the JMX JSON returned from the URL
"jmx?qry=Hadoop:service=NameNode,name=NameNodeInfo" malformed? What fields are
missing? It seems the {{workaround()}} function is trying to get the LiveNodes
and return them as an array that DataTables.js can consume. So if the node has
been dead long enough, it should *not* be in the LiveNodes list. If it is only
recently dead, which coloumn of data doesn't exist?
> After Datanode down, In Namenode UI Datanode tab is throwing warning message.
