Re: java.lang.NoSuchMethodError while writing to Kafka from Flink

Hi
1. You could check whether the 'org.apache.flink.api.java.clean' is in
your classpath first.
2. Do you follow the doc[1] to deploy your local cluster and run some
existed examples such as WordCount?

Please double-check that your distribution and application jar were
built against the same Flink version.

This looks related to a binary-compatibility issues reporter in
FLINK-13586 .
