Subject Re: Installing Cassandra Multinode on CentOs coming up with exception
Date Tue, 26 Aug 2014 09:37:39 GMT
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
