Setup three_data_hall FDB cluster

I setup a three_data_hall FDB cluster. The fdbcli command can connect to the keyspace, but I could not connect to the cluster using FDB Java client.

Is there a parameter I need to set to the FDB Java client for it to connect to the cluster under this mode?

The API version I used in my setup is 620.
FDB version is 6.2.27.
