Hi Mark,
Yes I was generating my own cassandra.yaml with the configuration mentioned
below,
cluster_name: 'node'
initial_token: 0
num_tokens: 256
seed_provider:
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
- seeds: "192.168.1.32"
listen_address: 192.168.1.32
rpc_address: 0.0.0.0
endpoint_snitch: RackInferringSnitch
Similarly for second node
cluster_name: 'node'
initial_token: 2305843009213693952
num_tokens: 256
seed_provider:
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
- seeds: "192.168.1.32"
listen_address: 192.168.1.36
rpc_address: 0.0.0.0
endpoint_snitch: RackInferringSnitch
and so on. . .
But even if I use default xml with the necessary configurational changes I
am getting following error.

Thanks!
