Hi Sasha,
This is what I am trying . I can sense this is happening with JDBCDriver stuff.
public static void main(String[] args) {
try {
java.sql.Connection con = null;
Class.forName("org.apache.cassandra.cql.jdbc.CassandraDriver");
con = DriverManager
.getConnection("jdbc:cassandra:root/root@localhost:9160/Key1");
// con.
System.out.println(con !=null);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
Getting following error:
org.apache.cassandra.config.ConfigurationException: Cannot locate cassandra.yaml
at
org.apache.cassandra.config.DatabaseDescriptor.getStorageConfigURL(DatabaseDescriptor.java:111)

Ideally it should get it . Not sure what is the issue.

Hi Vivek,
When I write client code in Java, using Hector, I don't specify a
cassandra.yaml ... I specify the host(s) and keyspace I want to connect to.
Alternately, I specify the host(s) and create the keyspace if the one I would
like to use doesn't exist (new cluster for example). At no point do I use yaml
file with my client code....
The conf/cassandra.yaml is there to tell the cassandra server how to behave /
operate when it starts ...
