Assuming you mean that you have multiple Hive installations (HDFS + Hive Metastore), yes you can access all of them from a single Presto query. Simply, add a hive catalog file (with a different name) for each cluster. See https://prestodb.io/docs/current/connector/hive.html for more information on setting up connections to hive.
