Carl, I tried and found ALTER TABLE SET LOCATION command can't be used to set location for non-native tables. In my case, where all hive tables are mapped with tables in hbase, ALTER TABLE SET LOCATION was not possible!! I agree it wasn't a good idea though but only option i believe
or is it available with any newer hive release?
