A couple of weeks ago I spent a bunch of time trying to get EMR + S3 + Avro working: https://forums.aws.amazon.com/thread.jspa?messageID=398194񡍲
Short story, yes I think PIG-2540 is the issue. I'm currently trying to get pig 0.10 running in EMR with help from AWS support. You have to do: --bootstrap-action s3://elasticmapreduce/bootstrap-actions/run-if --args "instance.isMaster=true,s3://yourbucket/path/install_pig_0.10.0.sh" install_pig_0.10.0.sh contents: --------------------- #!/usr/bin/env bash cd /home/hadoop wget http://apache.mirrors.hoobly.com/pig/pig-0.10.0/pig-0.10.0.tar.gz tar zxf pig-0.10.0.tar.gz mv pig-0.10.0 pig echo "export HADOOP_HOME=/home/hadoop" >> ~/.bashrc echo "export PATH=/home/hadoop/pig/bin/:\$PATH" >> ~/.bashrc cd pig ant cd contrib/piggybank/java ant cp piggybank.jar /home/hadoop/lib/. cd /home/hadoop/lib wget "http://json-simple.googlecode.com/files/json_simple-1.1.jar"; ------------------ But note, I have NOT got around to testing this yet! If you do, and it works let me know :-) will On Fri, Nov 30, 2012 at 4:05 PM, meghana narasimhan < [email protected]> wrote: > Oh I should also mention piggybank : 0.9.2-cdh4.0.1 > > > On Fri, Nov 30, 2012 at 12:59 PM, meghana narasimhan < > [email protected]> wrote: > > > Hi all, > > > > Is this bug https://issues.apache.org/jira/browse/PIG-2540 applicable to > > plain ec2 instances as well.
