Hi Sachin,
Flink 1.8 series have already been out of support, have you tried with a newer
version of Flink?

org.apache.flink.api.common.ExecutionConfig on EMR
Hi,
We have installed a flink cluster version 1.8.0 on AWS EMR.
However when we submit a job we get the following error:
(Do note that when we submit the same job on a local instance of Flink 1.8.1 it
is working fine.
The fat jar we submit has all the flink dependencies from 1.8.0 including the
class org.apache.flink.api.common.ExecutionConfig).
