I'm using AWS's EMR (hadoop as a service), and one step copies some data from EMR -> my cassandra cluster. I used to patch EMR with pig 0.11, but now AWS officially supports 0.11, so I thought I'd give it a try. I was having issues. The AWS forum on it is here: https://forums.aws.amazon.com/thread.jspa?threadID=131212
But the crux seems to be: I need to have pig.jar on the hadoop classpath, and AWS doesn't install it there. (/home/hadoop/lib is where all hadoop lib's live, and amazon installs pig into /home/hadoop/lib/pig). Does this make sense, or not? will
