Subject Re: asm IllegalArgumentException with 1.0.0
Date Mon, 14 Mar 2016 20:16:46 GMT
Yes pretty much - we use sbt to run the job in a local environment, not
Intellij, but should be the same thing. We were also seeing that exception
running unit tests locally. We did not see the exception when assembling a
fat jar and submitting to a remote Flink cluster.

It seems like the flink-connector-elasticsearch jar should not have shaded
classes in it. Maybe that jar in maven central was built incorrectly?

We worked around this by just not depending on that elasticsearch connector
at all, since we wrote our own connector for Elasticsearch 2.x.
