Subject DataNodeRegistration Serialization
Date Sat, 22 Mar 2014 20:16:44 GMT
Hi everyone,

I'm currently working on an application that requires some important
details about the DataNode registration (w/ NameNode) procedure.

Specifically, I have understood (after Wireshark-ing and looking through
the Hadoop code) that the DataNode is registered with the NameNode using a
single packet which tells the NameNode where the DataNode is "located"
(i.e. host and port).

However, in this packet, I'm not clear as to what scheme is used to
serialize the DataNode information. I am running Hadoop 1.2.1. Any
information will be appreciated.

Thank you,

Dhaivat Pandya
