Hello @Manoj-py,
thanks for contacting our community. I think this is not a problem of RocksDB. This error clearly state that JVM(Probably running Apache Flink) can't find class at all. It's clearly Maven dependency issue or Apache Flink Issue.
My bet is that you wrote job, which is executed on computation node which have different class path. It used to be problem with all distributed map-reduce systems(Hadoop, Apache Apark, ...) . You need to pay attention to which code you execute locally with probably maven POM classpath and which code is shipped on computation node where you don't have all the dependencies.
