Hi Sathi, the last error indicates that you are running Flink on a cluster with an incompatible Hadoop version. Please make sure that you use/build Flink with the Hadoop version you have running on your cluster. Especially make sure that the Hadoop version Flink is built for is compatible with the respective EMR version.
