Hi Aditya,

What do you mean by "addressing from memory"? Note that its difficult
for us to answer your questions perfectly if you don't also specify
exactly what you are looking to do and some of why.

In any case, assuming you're use the maintenance 1.x release of HDFS
that does not have HA, you can look at the sources if you're
interested in the nitty gritty details:
http://svn.apache.org/repos/asf/hadoop/common/branches/branch-1/src/hdfs/org/apache/hadoop/hdfs/server/namenode/SecondaryNameNode.java.
Sources are also available in the tarball of your Hadoop version.
