Hi Jerry, There's no need for additional HBase configuration when using HDFS HA, as it works as an HDFS client and RS will reach NN through nameservice configured on hdfs-site, and once both active and standby NNs have an up to date image of HDFS state, during a failover the transition between NNs is transparent for clients (including HBASE).
