eldho on "Error on 'select * from' after Bulk Upload using SSTable"

I am a newbie in Cassandra world. I was trying to bulk upload some data to Cassandra. I ran sstableloader to get the following output. I use cassandra 1.2

Streaming revelant part of /home/ubuntu/software/apache-cassandra-1.2.5/data/sugar_cookie_prod/ja_job_master/sugar_cookie_prod-ja_job_master-ic-1-Data.db to [/127.0.0.1]
progress: [/127.0.0.1 1/1 (100)] [total: 100 – 0MB/s

however when I try querying the table from cqlsh I get the following error:

Request did not complete within rpc_timeout

my rpc address in cassandra port is 0.0.0.0
I have been stuck in same postition for 2 days and I need to resolve this to proceed.
-Thanks
