To check that the authentication works, try using the Trino CLI tool:
-
Connect to Trino Coordinator with specific parameters:
$ ./trino https://<coordinator_host>:18188 --keystore-path <keystore-path> --keystore-password <keystore_password> --truststore-path <truststore-path> --truststore-password <truststore_password> --user=<username> --password -
Enter a password when prompted.
-
Once the Trino shell is active, run the
SHOW CATALOGS;command. The output should be similar to the following:Catalog ------------- hive-adh iceberg-adh system (3 rows) Query 20250306_005901_00001_6smm5, FINISHED, 1 node Splits: 7 total, 7 done (100.00%) 0.28 [0 rows, 0B] [0 rows/s, 0B/s]
