When Hive-thriftserver with DSE integration starts, it starts our custom
Hive metastore which uses a Cassandra client to access Cassandra. The Cassandra
client takes the username/password configuration settings to access Cassandra
nodes. Another use case is connecting to thrift server through Beeline and
passing the username/password. In this use case, Cassandra client has to use
hiveconf to get the username/password per user session. That's the reason we
can't simply read it through system properties.
RelationProvider is not involved during Hive metastore startup, so I am
afraid that it can help for our case.
