running pillar command line get "All host(s) tried for query failed" error

[arvindclement]

Hey Guys we looking to implement pillar so built the rpm and installed it but when I try to initialize it against my cluster I get the below error
pillar -e dev initialize <my_keyspace_name>
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
All host(s) tried for query failed (tried: 10.102.92.220:9042 (null))

conf file is given below

This file is used in development and test. It is included in the distribution as an example.

pillar.<my_keyspace_name> {
dev {
cassandra-seed-address: "10.102.92.220"
cassandra-keyspace-name: "my_keyspace_name"
auth {
username: cassandra
password: cassandra
}

}

am I missing something? Any help would be great
