Hi. I am getting following error if I use datastax(Cassandra driver) with Elasticsearch Transport client. Does this have to do with race conditons ? Could you please provide some advice, solutions or documentations ?
java.lang.AbstractMethodError: io.netty.util.concurrent.MultithreadEventExecutorGroup.newChild(Ljava/util/concurrent/Executor;[Ljava/lang/Object;)Lio/netty/util/concurrent/EventExecutor

Thanks in advance.

I think you have conflicting versions of Netty, namely at least a version different than the Elasticsearch client expects or the Cassandra client expects.
