Yes you need to update the metastore db directly for this to be in effect.

Subject: alter external table location with new namenode address
We have hive external table mapped to hbase, now moving
from pseudo distributed to fully distributed hadoop cluster.
found that hive queries are still pointing to older namenode address
ie: hdfs://localhost:9000/user/hive/warehouse/<table-name> as it stores
full uri in its derby metastore.
Q . what would be the best way to set new namenode address?
Alter table command on hive shell to set hdfs location is only
possible for native tables!!
should i update derby "DB_LOCATION_URI" column directly?
Your help/suggestion is highly appreciated
