Hello,
I am trying to integrate cassandra into Hadoop and PIG and trying to load
CSV file into Cassandra using PIG Script. Can someone help ?

I think you need to send that details file for us to give you more
information:
/home/hduser/apache-cassandra-2.0.9/examples/pig/pig_1406808480077.log
pig stores its runtime exceptions in a main details file that has the guts
of the problem.
Also, try posting to the pig user list.

I'm wondering how many people are using cassandra + pig out there? I
recently went through the effort of validating things at a much higher
level than I previously did(*), and found a few issues:
https://issues.apache.org/jira/browse/CASSANDRA-4748

, it sounds like there are some
rough edges like you say. But issues that are reproducible on tickets for any
problems are much appreciated and they will get addressed.

I think that your best bet is to look directly into the source tarball
https://www.apache.org/dyn/closer.cgi?path=/cassandra/1.0.8/apache-cassandra-1.0.8-src.tar.gz
or in the git repository
http://git-wip-us.apache.org/repos/asf/cassandra.git

The tokens alternate between the two datacenters.
I have hadoop installed as tasktracker/datanodes on the

There is another non cassandra node that is used as the hadoop
Yes it's read repair you can lower the read repair chance to tune this.

It'd be great if we had different settings for inter- and intra-DC read repair.

Pig do not have thrift interface, But I believe you can create it. And
another way I think is create a web service for your pig service, and
call the web service in your php.

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.

AFAIK you can submit a pig job to the Hadoop job server via the pig command
line interface. If you have not done so already have a read of the Hadoop Book
it discusses pig as well

did you register cassandra jars with Pig. This seems like a class

Details of basic linkage are in the contrib/pig section of the
Cassandra source in the readme. You should be able to run basic
queries with just that.
