ASF GitHub Bot logged work on BEAM-5441: ---------------------------------------- Author: ASF GitHub Bot Created on: 21/Sep/18 15:22 Start Date: 21/Sep/18 15:22 Worklog Time Spent: 10m Work Description: tweise commented on issue #6461: [BEAM-5441] extend primitive transform check to find subtransform leaves URL: https://github.com/apache/beam/pull/6461#issuecomment-423571589 @mxm @angoenka @ryan-williams I just tried this PR on top of master and verified that this fixes the issue with running wordcount. I see that a single container is started for the pipeline and that the pipeline succeeds, with local file system, as expected. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
