[GitHub] [kafka] ableegoldman opened a new pull request #11364: MINOR: expand logging and improve error message during partition count resolution
ableegoldman opened a new pull request #11364:
URL: https://github.com/apache/kafka/pull/11364
Recently a user hit this TaskAssignmentException due to a bug in their regex that meant no topics matched the pattern subscription, which in turn meant that it was impossible to resolve the number of partitions of the downstream repartition since there was no upstream topic to get the partition count for. Debugging this was pretty difficult and ultimately came down to stepping through the code line by line, since even with TRACE logging we only got a partial picture.
We should expand the logging to make sure the TRACE logging hits both conditional branches, and improve the error message with a suggestion for what to look for should someone hit this in the future
