I'm using cloudera CDH5 with Pig 0.13 ( tried Pig 0.12.1 as well ) and I'm building my own custom loadFunc and I have a simple script that just load using the new loadFunc.
When running in local
mode everything works fine and the output is correct.
But when running in mapreduce
mode ( still locally ), I get the error:
Unable to open iterator for alias output_hash

I tried setting the properties verbose to true or traces to debug, but didn't didn't get useful info.
Any insights on how to resolve or debug this ?
