Hi, I try to use a merge join for 2 bags. Here is my pig code: http://pastebin.com/Y9b2UtNk .
But I got this error: Caused by: org.apache.pig.backend.hadoop.executionengine.physicalLayer.LogicalToPhysicalTranslatorException: ERROR 1103: Merge join/Cogroup only supports Filter, Foreach, Ascending Sort, or Load as its predecessors. Found I think the reason is that there is no sort function or something like this. But the bags are definitely sorted. How can I do the merge join? thanks
