I'm having cluster of Cassandra nodes with Spark worker on each node machine. For communication I'm using Datastax Spark-Cassasndra connector. Does the Datastax connector have optimisation for reading of data from Cassandra node by worker in same machine or exists some dataflow betweens machines?

Yes. It indeed does.
It is explained in this document. http://www.slideshare.net/SparkSummit/cassandra-and-spark-optimizing-russell-spitzer-1
