Github user rmetzger commented on the pull request: https://github.com/apache/flink/pull/1342#issuecomment-155768292 Thanks a lot for working on this issue! It doesn't happen everyday that users identify issues, fix them and verify the fix so properly :) I would really like to avoid pulling hbase as dependency into Flink's binary distribution. Can you change to "obtain token" part to do everything by loading the classes dynamically and calling the methods via reflection? (Similar to Spark's implementation: https://github.com/apache/spark/pull/5586/files) This way, we only execute this if the hbase classes are in the classpath.
