As mentioned in the #cassandra IRC channel - there's going to be a dinner in
Austin on July 15th for people interested in Cassandra.

Sounds like what you're seeing is in the client, but there was another

Looks like Cassandra is now supported by the whirr incubator project now.

When Jonathan said don't build trunk thrift, he meant just thrift - apply the

The revision number is appended to the thrift jar in the cassandra lib folder.

Can't you just execute a Pig script with PHP by calling Pig with a PHP exec
function call? I'm not sure what you're trying to do with it, but that's one
way you could do it.

Yes - the HadoopSupport should be updated for the functionality that is added
to 0.7. It's still a little in flux. There is an output format and output

the contrib/word_count example code. The output streaming, whi

I would first see if the unmodified version of the word count example works for

it's more of a "let's get 0.21 release out the door so we can move on" type of

I think it's just a classpath issue with os x. I've had it do that for me as
well, but it runs just fine from IntelliJ IDEA. I had thought my own system
was just somehow messed up. I'll do some checking and try to respond to the

So final answer - known issue with RC1 -
https://issues.apache.org/jira/browse/CASSANDRA-1781 - that should be fixed
before 0.7.0 is completed.
