This is a Hive Metastore health test that checks that a client can connect and perform basic operations. The operations include: (1) creating a database, (2) creating a table within that database with several types of columns and two partition keys, (3) creating a number of partitions, and (4) dropping both the table and the database. The database is created under the /user/hue/.cloudera_manager_hive_metastore_canary/<Hive Metastore role name>/ and is named "cloudera_manager_metastore_canary_test_db". The test returns "Bad" health if any of these operations fail. The test returns "Concerning" health if an unknown failure happens. The canary publishes a metric 'canary_duration' for the time it took for the canary to complete. Here is an example of a trigger, defined for the Hive Metastore role configuration group, that changes the health to "Bad" when the duration of the canary is longer than 5 sec: "IF (SELECT canary_duration WHERE entityName=$ROLENAME AND category = ROLE and last(canary_duration) > 5s) DO health:bad" A failure of this health test may indicate that the Hive Metastore is failing basic operations. Check the logs of the Hive Metastore and the Cloudera Manager Service Monitor for more details. This test can be enabled or disabled using the Hive Metastore Canary Health Test Hive Metastore monitoring setting.

Yes, the first interpreter will be the main one. This is the best to have it globally for everyone. Changing the default interpreter by clicking on the star is more a per-user basis.
