Greetings   If by chance u are still looking to resolve  a return code 2 error while tunning hive, I may have a solution for u if u dont get any information from the log files.  Return code 2 is basically a camoflauge for an hadoop/yarn memory problem.  Basically, not enough resources configured into hadoop/yarn to run your projects   If u are running a single-node cluster ..see the link below   http://stackoverflow.com/questions/26540507/what-is-the-maximum-containers-in-a-single-node-cluster-hadoop   U may be able to tweak the settings depending on your cluster setup.  If this does not cure your problem 100%, then at least the return code 2 or exit code 1 errors would disappear.   Hope this helps ...
