title: Access table in other than default scheme (database) from sparklyr
body: <p>After I managed it to connect to our (new) cluster using <code>sparklyr</code> with <code>yarn-client</code> method, now I can show just the tables from the default scheme. How can I connect to <code>scheme.table</code>?
  Using <code>DBI</code> it's working e.g. with the following line:
  <code>dbGetQuery(sc, "SELECT * FROM scheme.table LIMIT 10")</code>
  In HUE, I can show all tables from all schemes.</p>
