Push up filter does not account for added columns in foreach ------------------------------------------------------------
Key: PIG-877 URL: https://issues.apache.org/jira/browse/PIG-877 Project: Pig Issue Type: Bug Affects Versions: 0.3.1 Reporter: Santhosh Srinivasan Fix For: 0.3.1 If a filter follows a foreach that produces an added column then push up filter fails with a null pointer exception. {code} ... x = foreach w generate $0, COUNT($1); y = filter x by $1 > 10; {code} In the above example, the column in the filter's expression is an added column. As a result, the optimizer rule is not able to map it back to the input resulting in a null value. The subsequent for loop is failing due to NPE. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
