Hi Suchithra, I suspect you want to connect to something like HDFS from the running k8s application. Is this correct? Yangze already gave some good hints you have to make sure that the necessary Hadoop java libraries and configurations are part of your Flink docker images or are mounted from an external filesystem. [1] If the Hadoop jar files are present in your image you can set the environment variable $HADOOP_CLASSPATH to point to the jar location.
I hope that helps, please share more information about your setup if this solution does not suffice. Best, Fabian [1] https://ci.apache.org/projects/flink/flink-docs-release-1.11/ops/deployment/hadoop.html#providing-hadoop-classes
