I believe what I did was when I set up Oozie with the setup script where you specify the version of Hadoop and such, I also added additional jars like the Cassandra jars and some of its dependencies there and the cassandra.yaml, cassandra-env.sh and potentially the topology properties file. Then with the configuration outlined on the Cassandra wiki that you posted, I just used the built-in Pig support and it worked fine. You might try a simple test case to read from and write to Cassandra and look for errors either in the job setup (the 1 mapper job that Oozie creates to initialize the job) or in the job itself.
The specific jars from Cassandra that I added as additional jars were: cassandra-all cassandra-thrift guava high-scale-lib lib-thrift log4j snake-yaml commons-io then cassandra.yaml, cassandra-env.sh, and cassandra-topology.properties file (if using property file snitch) I reference those jars in the environment variable LIBEXT_JARS then execute: bin/oozie-setup.sh prepare-war -jars $LIBEXT_JARS -extjs ./ext-2.2.zip Hopefully that helps, Jeremy On 28 Nov 2013, at 15:31, Miguel Angel Martin junquera <mianmarjun.mailingl...@gmail.com> wrote: > hi Jeremy, > > I do not try test it still, I only test examples pig from oozie project > without cassadra. > > * pig-cassandra* sets the cassandra pig libraries .jar in the the > PIG_CLASSPATH env var. and after call the original shell script *pig* from > PIG_HOME/bin/pig and , up to now, I launch pig scripts with pig_cassandra > directly. > > I do not know and did not see how oozie launch pig and I supose that Oozie > launch the PIG_HOME/bin/pig. > > If you are using this config and the pig scripts that use cassandra works > fine , I suspose that the trick is putting the cassandra jars > dependencies and other udf or libraries that you use in the pig scripts in > the oozie sharelib or in the lib folder of the job. > > > On the other hand, I do not know if i have to configure some thing like > this. > > http://wiki.apache.org/cassandra/HadoopSupport#Oozie > > I am using Cassandra 1.2.10, Oozie 4.0.0 adn pig 0.11.1. > > I try to test these options and see if it works- > > Thanks in advance > > > > > > > > > > > > 2013/11/28 Jeremy Hanna <jeremy.hanna1...@gmail.com> > >> If I remember correctly when I configured pig, cassandra, and oozie to >> work together, I just used vanilla pig but gave it the jars it needed. >> >> What is the problem you’re experiencing that you are unable to do this? >> >> Jeremy >> >> On 28 Nov 2013, at 12:56, Miguel Angel Martin junquera < >> mianmarjun.mailingl...@gmail.com> wrote: >> >>> 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 job that runs ./pig-cassandra script.pig >>> or changing environment variables vakues >>> or the original to include the pig-cassandra code .... etc >>> >>> Thanks and regards >> >>
