Hi Pratyush,

First, this list will be closed in the future. The list for these kind of  
questions is the Thrift user list at Apache (incubator). You can join this  
list by sending an e-mail with subject 'subscribe' (without the quotes) to:
thrift-user-request@incubator.apache.org

There is not much documentation yet. But to get started you will need the  
following information:
- the Thrift file containing the definition of the structures, services,  
etc. of hypertable
- the details about the transport and protocol used by hypertable:
   - transport: which port is used?
   - transport: is it a raw TCP socket or over HTTP?
   - protocol: is the binary, JSON or maybe a custom serialization protocol  
used?

Once you have this information you can use the Thrift compiler to generate  
Java classes for you. Run the compiler without arguments to get help:
   <path to compiler>/thrift -gen java:beans

After generating the Java classes you can add them to your project. Use  
the classes in the Thrift Java libary to setup a connection over which the  
generated classes will communicate. For an example see the sources of the  
test classes in 'test/java'. You can check out the source code from:
   http://svn.facebook.com/svnroot/thrift/trunk

Kind regards,

Does Hypertable have a Thrift interface already? If it doesn't you'll  
need to code the interface spec yourself and then write the code to  
translate from the Thrift API calls to whatever internal calls  
Hypertable uses. In HBase we implemented this as a layer outside the  
regular services for the sake of simplicity. That is, there's a  
separate Thrift server that run as a gateway for HBase client requests.

(Incidentally, what in particular was wrong with HBase that you're  
headed to the Hypertable camp? Do we already know about it on the  
HBase list?)
