Description
HMS exposes these two databases "sys" and "information_schema" which contain tables that expose the underlying meta information in a queryable format. However, Impala cannot read them because they come with custom serde that Impala doesn't support.
From a usability point of view, we should black list those databases from loading, so that users don't see them when querying the database list. I think that is reasonable because they can't query them anyway.
