Subject [jira] [Commented] (HADOOP-11575) Daemon log documentation is misleading

--------------------------------------------

Hi [~aw],
Initially even i was thinking about the same, but in log4j terms they call it as log itself
and interface definitions also finally narrow  down to {{LogFactory.getLog(String name)}
Also in some places in the code they have used the log created from one class name is used
in other classes also . For instance Log in the Name node class is used in many other classes
and one such class being : DatanodeManager.registerDatanode
bq.  NameNode.LOG.info("BLOCK* registerDatanode: " + nodeN);
Hence kept it as "Log Name" itself

bq.Back ticks. See Federation.md and search for dfsclusterheatlth.jsp for an example.

bq. Should we consider deprecating this servlet and provide a REST API instead?
