title: Understand Intermittent SSL error from dbGetQuery
body: <p>I can use some help understanding the following intermittent error we get w/ an R/shiny app deployed to rs-connect from RStudioPro.</p>
  <p>The calling code (which usually works) is</p>
  <pre><code>RAW &lt;-
      dbGetQuery(imp_connect, &quot;SELECT * from XXXX.XXXXX&quot;)
  </code></pre>
  <p>imp_connect is the connection object and correctly formatted. The ocassional error is:</p>
  <blockquote>
  <p>Warning: Error in .verify.JDBC.result: Unable to retrieve JDBC result set for SELECT * from XXXX.XXXXX ([Simba]ImpalaJDBCDriver ERROR processing query/statement. Error Code: javax.net.ssl.SSLException: Connection has been shutdown: javax.net.ssl.SSLException: java.net.SocketException: Connection
  reset, SQL state: HY000, Query: SELECT * f()()rom XXXX.XXXXX.)</p>
  </blockquote>
  <p>Any suggestions or referrals are quite welcome.</p>
