Basically right. more precisely it depends on how individual interpreter you use is implemented. For example, hive interpreter shipped in Zeppelin uses hive-jdbc driver to connect to hiveserver2. So in this case Zeppelin will only need to connect to the node where hiveserver2 runs. not entire cluster.
