> The runTestQuery() in the org/apache/hadoop/hive/metastore/MetaStoreDirectSql.java is using a test query
> {code:java}
> select "DB_ID" from "DBS"{code}
> to determine whether the direct SQL can be used.
> With larger deployments with many (10k+) Hive databases it would be more efficienct to query a small table instead, for example the "VERSION" table should always have a single row only.
