If both `show databases` and `show tables` are OK, and the above error
occurs when querying, we need to perform the following two operations:
- Core-site.xml and hdfs-site.xml need to be placed in the fe/conf and
be/conf directories
- The BE node executes the kinit of Kerberos, restarts the BE, and then
executes the query.
+
+11. If the `show tables` is normal after creating the Hive Catalog, but the
query report `java.net.UnknownHostException: xxxxx`
+
+ Add a property in CATALOG:
+ ```
+ 'fs.defaultFS' = 'hdfs://<your_nameservice_or_actually_HDFS_IP_and_port>'
