Hi,
For cassandra 2.0, DSE 4.0 come with casandra 2.0.5
For cassndra 1.2, DSE 3.1 come with cassandra 1.2.6
you should wait at least version 2.1.5

You have you upgrade to 1.2.9 first.

- Java 7 is now *required*!
- Upgrading is ONLY supported from Cassandra 1.2.9 or later. This

you have to check listen_address in cassandra.yaml, change the localhost

Hi aaron,
I was sure that phpcassa use QUORUM for W and R by default, but you're
right, the default CL for R AND W is ONE.

that always return inconsistent data.

Hi chiddu,
You have to configure your operating system to use the Oracle JRE instead
of OpenJDK.
