Eugene Kirpichov created BEAM-1979: -------------------------------------- Summary: Outputting to an undeclared side output TupleTag should throw Key: BEAM-1979 URL: https://issues.apache.org/jira/browse/BEAM-1979 Project: Beam Issue Type: Bug Components: runner-dataflow Reporter: Eugene Kirpichov Assignee: Eugene Kirpichov
Currently some runners (perhaps all of them?..), when you output to a side output tag that wasn't passed to ParDo.withOutputTags, simply drop the data on the floor (or increase some aggregators). Silent data dropping is never okay, and it's never okay to output to an undeclared tag. So instead this should throw. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
