Subject Get Hadoop cluster topology
Date Tue, 16 Apr 2013 18:04:11 GMT
I understand that when Namenode starts up it reads fsimage to get the state
of HDFS and applies the edits file to complete it.

But how about the cluster topology ? Does the namenode read the config
files like core-site.xml/slaves/... etc to determine its cluster topology
or uses an API to build it.
