That path is reliable but we would recommend not using that path in general. 
That's your workspace root storage.

Your data should be in a cloud path of your choosing (s3/adls/gcs) so that you can separate your data out by BU/Project/team etc based on what buckets each one owns.

When you create a schema in HMS you can do

CREATE SCHEMA A LOCATION 's3 path';

Then when you create a table in that Schema, it will be a managed table in a sub-path of the above path.
Now it's not tied to workspace root storage.
