[jira] [Commented] (FLINK-6294) BucketingSink throws NPE while
cancelling job

Aljoscha Krettek commented on FLINK-6294:
-----------------------------------------
I created a test job that uses {{BucketingSink}} and followed your steps to try and reproduce the problem. I didn't manage to do so. What's your exact Flink version? On my dashboard it says Flink 1.2.0, commit 1c659cf.
