Re: Error when use tow datasink

This looks like a dependency issue of the asm dependency.
Did you upgrade all flink dependencies to the 0.8.1 version?
I think you also refresh / reimport the project in your IDE so that it can
pick up the new dependencies.

Hi,

which version of Flink are you using?
Since 0.8.0, Flink supports disjoint dataflows (
https://issues.apache.org/jira/browse/FLINK-820).
