Installing Cassandra Multinode on CentOs coming up with exception
Hi All,
I am installing Cassandra Multinode Setup on a 4 node CentOs Cluster, my
cassandra.yaml looks like so
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 cassandra.yaml 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. . .
While trying to start the Server running on the Seed node(192.168.1.32) it
throws this nasty exception and didn't start,

Invalid yaml
I am not sure exactly whats making it to throw NullPointer and halt the
process.
Expert Advice would be appreciated!
URGENT!
Thanks!

Hey Patricia,
Thanks for your kind response. I will surely take care of that provided the
use of virtual nodes.
Thanks again!

Vineet,
One more thing -- you have initial_token and num_tokens both set. If you
are trying to use virtual nodes, you should comment out initial_token as
this setting overrides num_tokens.

Re: Installing Cassandra Multinode on CentOs coming up with exception
Posted by Vivek Mishra <mi...@gmail.com>.
Please read about http://www.yaml.org/start.html.
Looks like formatting issue. You might be missing/adding incorrect spaces
Validate your YAML file. This should help you out

Re: Installing Cassandra Multinode on CentOs coming up with exception
Posted by Vineet Mishra <cl...@gmail.com>.
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.

Invalid yaml
Could you figure out whats making the yaml invalid.
Thanks!

Re: Installing Cassandra Multinode on CentOs coming up with exception
Posted by Mark Reddy <ma...@gmail.com>.
You are missing commitlog_sync in your cassandra.yaml.
Are you generating your own cassandra.yaml or editing the package default?
If you are generating your own there are several configuration options that
are required and if not present, Cassandra will fail to start.
Regards,
Mark

Thanks Mark,
That was indeed yaml formatting issue.
Moreover I am getting the underlying error now,

Re: Installing Cassandra Multinode on CentOs coming up with exception
Posted by Mark Reddy <ma...@gmail.com>.
It is telling you that your yaml is invalid, from looking at the snippet
you have provided it looks like the seed_provider.parameters is not
correctly indented, it should look something like:
seed_provider:
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
- seeds: "192.168.1.32"
Regards,
Mark
