Hi Vishan, Aron and all, Thanks for the help. I tried it and successfully worked for me. But I could not find a place where mention about the attributes of some commands.
e.g. update column family <cf> [with <att1>=<value1> [and <att2>=<value2> ...]]; create keyspace <keyspace> [with <att1>=<value1> [and <att2>=<value2> ...]]; (we can use comparator=UTF8Type and default_validation_class=UTF8Type as changed attributes) Is there any documentaries which mentioned about those applicable attributes in each case? thanks Eranda P.S. I put a blog post on Cassandra-cli in http://emsooriyabandara.blogspot.com/ please correct me if I am got it wrong in any place
