Datastax service doesn't start after configuring cassandra.yaml for creating a cluster

Question

I am having a problem with configuring my cluster in Cassandra in DSE 5.0. After I change the /etc/dse/cassandra/cassandra.yaml the service dse (sudo service dse start) doesn't start. I am a beginner so I don't know what to do.

Node1:

cluster_name: 'MyCluster'  
num_tokens: 256  
seed_provider:  
    - class_name: org.apache.cassandra.locator.SimpleSeedProvider
      parameters:
          - seeds: "10.1.4.48,10.1.4.49"

listen_address: 10.1.4.48  
broadcast_address: 10.1.4.48  
rpc_address: 0.0.0.0  
broadcast_rpc_address: 10.1.1.48   

Node2:

cluster_name: 'MyCluster'  
num_tokens: 256  
seed_provider:  
    - class_name: org.apache.cassandra.locator.SimpleSeedProvider
      parameters:
          - seeds: "10.1.4.48,10.1.4.49"

listen_address: 10.1.4.49  
broadcast_address: 10.1.4.49  
rpc_address: 0.0.0.0  
broadcast_rpc_address: 10.1.1.49

This is what I have changed in each of the two nodes that I want to put in the same cluster. Maybe I need to change another file also?

Answer 1

The yaml file format can be very fussy. I usually grab a vanilla cassandra.yaml one from an install (same version) and run a diff

You may well see some unexpected differences. The most common one is a missing space between the : and <value> so for example

listen_address:192.168.56.20

instead of

listen_address: 192.168.56.20
