- Sometimes, an Impala query might run for an unexpectedly long time,
- tying up resources in the cluster. You can cancel the query explicitly,
- independent of the timeout period, by going into the web UI for the
- <cmdname>impalad</cmdname> host (on port 25000 by default), and using
- the link on the <codeph>/queries</codeph> tab to cancel the running
- query.

- Various client applications let you interactively cancel queries
- submitted or monitored through those applications. For example:
- <ul>
- <li>
- Press <systemoutput>^C</systemoutput> in
- <cmdname>impala-shell</cmdname>.

- Click <b>Cancel</b> from the <b>Watch</b>page in Hue.

+ <conbody>
+ <p>An Impala administrator can set a default value of the
+ <codeph>EXEC_TIME_LIMIT_S</codeph> query option for a resource pool.
+ If a user accidentally runs a large query that executes for longer
+ than the limit, it will be automatically killed after the time limit
+ expires and frees up resources. </p>
+ <p>Users can override the default value per query or per session if they
+ do not want the default <codeph>EXEC_TIME_LIMIT_S</codeph> value to
+ apply to a specific query or a session. See <xref
+ href="impala_exec_time_limit_s.xml#exec_time_limit_s"/> for the
