What component are you asking about? What are you trying to achieve?

They typically call each other over combinations of separate protocols.

- HDFS and YARN interact via RPC/IPC.

- Ambari Server and Agents are over HTTP & REST. Ambari also needs JDBC connections to the backing database.

- Hive, Hbase, and Spark can use Thrift Server. The Hive metastore uses JDBC.

- Kafka has its own TCP protocol.

I would suggest starting on a specific component for the use case(s) you want. Hadoop itself is only comprised of HDFS & YARN + MapReduce
