Hi all:
We have a Cassandra 1.2.10 pre-production ring integrated with Hadoop and
Pig and we are thinking to upgrade the system from 1.2.10 to 2.0.X ( to
2.0.4 for example) before we pass to production.
What are the Pros and Cons According to your experience?
Many thanks and Regards

Hi,
I have an error with pig action in oozie 4.0.0 using cassandraStorage.
(cassandra 1.2.10)
I can run pig scripts right with cassandra. but whe I try to use
cassandraStorage to load data I have this error:
*Run pig script using PigRunner.run() for Pig version 0.8+*
*Apache Pig version 0.10
experiencing that you are unable to do this?

hi all;
What is the best way to integrate cassandra pig-extension with oozie?
can be configure oozie to use pig-cassandra instead of pig?
Some ideas that I thinking are:
Launching a Shell jobthat runs ./pig-cassandra script.pig
or changing environment variables vakues
or the original to
#x27;QA', 30);
insert into test (id, title, age) values('6', 'QA', 30);
