I have some issues to continue with Exercise 14 : Hinted Handoff of DS201 : Foundation of Apache Cassandra and Datastax enterprises. Can you help to advise?
I shutdown the 2 nodes according to step 3. However, I'm unable to execute cqlsh on node1. It is unable to connect to 127.0.0.1.
I have tried to restart the 2 nodes and managed to connect using cqlsh on node1 then i shut down the other 2 nodes again.
I encountered NoHostAvailable at step 6.
Please help to advise
Hi likhia,
Please ensure you are connecting to the node that is still online by specifying the IP and port when you run cqlsh, for example:
cqlsh <IP> <port>
The port is typically 9042, but you can check the native_transport_port in the cassandra.yaml of the node that is online to confirm, let us know if you can't get it working.
In the previous exercise, there was a note that instructed you to specify the IP address + CQL port when connecting with cqlsh because in the DS201 course VM, the nodes are configured with different CQL ports:
$ for _node in node*; do echo "$_node - `grep ^native_transport_port $_node/resources/cassandra/conf/cassandra.yaml`"; done node1 - native_transport_port: 9041 node2 - native_transport_port: 9042 node3 - native_transport_port: 9043
If you don't specify the CQL port, cqlsh connects to the default 9042.
I suggest you review the instructions and try again. Cheers!
