DataStax Devcenter fails to connect to the remote cassandra database

Question

OS: CentOS 6.4 (server)

I have successfully installed (yum install dsc20) the cassandra database layer in my server and can connect to it using the CQL SHel (cqlsh).

Answer 1

In the cassandra.yaml, I set

1. listen_address: localhost
2. rpc_address: 1.2.3.4
3. broadcast_rpc_address: 1.2.3.4

After doing a

sudo service cassandra restart

DevCenter was able to successfully connect.

After this change, cqlsh would not start without the address:

cqlsh 1.2.3.4

You can set the environment variable $CQLSH_HOST=1.2.3.4. Then simply type cqlsh.
