title: HConnection Closed - JDBC - Connection-Pool
body: <p>We're using JDBC Connection through Hikari CP to connect to Apache Phoenix &amp; we're facing &quot;HConnection-Closed&quot; Issues. It's because of stale connections present in the pool and the pool does not get cleared until we restart the applications.</p>
  <p>Has anyone faced something like above (may not be same DB)?</p>
  <p>Is there any recommended approach to connect to Phoenix from Spring applications?</p>
