<h2>Sessions</h2>

<div class="alert alert-info" role="alert">
<h4>There are {{num_sessions}} sessions, of which {{num_active}} are active and
{{num_inactive}} are inactive</h4>
Active sessions are sessions that have not yet been expired or closed. Sessions are
expired by the Impala server when they are idle for some time (see Idle Timeout
below). Sessions can be closed in several ways: closed by the client, closed by this Web
UI or closed by the Impala after all client connections are disconnected and
-disconnected_session_timeout is exceeded. Sessions stay in the closed state
temporarily while queries in the session are cleaned up by the Impala server, after
which the session is removed from this list.</div>
