Daniel Dai commented on PIG-2166: --------------------------------- Hi, Hien, Patch looks good. For BagToString, it is better to have a default delimit, so it does not complain if we don't pass a delimit. It also makes sense to add some e2e tests to test/e2e/pig/tests/nightly.conf. You can use the input file studentcomplextab10k which contains bag. Refer to https://cwiki.apache.org/confluence/display/PIG/HowToTest for how to run e2e tests. > UDFs to join a bag > ------------------ > > Key: PIG-2166 > URL: https://issues.apache.org/jira/browse/PIG-2166 > Project: Pig > Issue Type: Improvement > Reporter: Daniel Dai > Assignee: Hien Luu > Priority: Minor > Labels: newbie, simple > Attachments: bagtotuplestring.diff > > > Get several request for a UDF to flatten a bag.
