Robert Metzger commented on FLINK-1601:
---------------------------------------
The errors reported by Till in the comments yesterday are from your
CliFrontend rewrite pull request (when the YARN tests were still failing). So
that was a valid case of failing tests.
I'm closing the issue for now because [~uce] was running the travis tests 20
times on master and they all suceeded.
