supportsPreferredIp

default boolean supportsPreferredIp()

Provide way to disable getPreferredIP() for tools without access to the system keyspace

CASSANDRA-17663 moves calls to SystemKeyspace.getPreferredIP() outside of any threads that are regularly interrupted. However the streaming subsystem is also used by the bulk loader tool, which does not have direct access to the local tables and uses the client metadata/queries to retrieve it.

Returns:

true if SystemKeyspace.getPreferredIP() should be used when connecting
