Dominik Bruhn commented on FLINK-5350:
--------------------------------------
I was running into this bug because I needed to use SASL/PLAIN on my Kafka
connections. Without this PR, it is not possible to provide an own JAAS config
property.
I tried out the PR works perfect and fixes the issues for me.
Would be happy to have this merged for 1.2
