null should be handled consistently in Join -------------------------------------------
Key: PIG-927 URL: https://issues.apache.org/jira/browse/PIG-927 Project: Pig Issue Type: Bug Affects Versions: 0.3.0 Reporter: Pradeep Kamath Currenlty Pig mostly follows SQL semantics for handling null. However there are certain cases where pig may need to handle nulls correctly. One example is the join - joins on single keys results in null keys not matching to produce an output. However if the join is on >1 keys, in the key tuple, if one of the values is null, it still matches with another key tuple which has a null for that value. We need to decide the right semantics here. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
