Is this not two different issues? - adding builds for Scala 2.12 - upgrading to Java version 1.8 It may be time to switch, but I haven’t seen anything in FLINK-5005 which prevents simply adding Scala 2.12 to our supported build matrix and continuing to build 2.10 / 2.11 against Java 1.7. Greg

Hi all, as promised in March, I want to revive this discussion! Our users are begging for Scala 2.12 support [1], migration to Akka 2.4 would solve a bunch of shading / dependency issues (Akka 2.4 will remove Akka's protobuf dependency [2][3]) and generally Java 8's new language features all spea

Hi Mu Kong, I think this is a problem with how the BucketingSink works. It keeps for each file a writer which has an open file stream. I think we should limit the number of open writers such that we don't run into the problem of too many open file handles/open HDFS connections. Could you open a J
