Hi guys, I just found I can't pass the Travis build due to some errors in flink-python module [1]. I'm sure my PR has nothing related with flink-python. And there are also a lot of builds are failing on these errors.
I have rebased master branch and tried several times. But it doesn't work. Could somebody who is familiar with flink-python module take a look at this failure? 1. https://travis-ci.com/flink-ci/flink/jobs/229989235 Thanks, Biao /'bɪ.aʊ/
