How to set the timeout of Kyuubi Sessions?

[HaoYang670]

Hi! Is there a way to set the timeout for Kyuubi sessions? For example, if I run spark.stop to delete the Kyuubi engine, how long will be the Kyuubi sessions removed?

[yaooqinn]

yes, please check the doc

[HaoYang670]

No, if I use spark.stop, the sessions will be dangling.

I mean timeout is not automatically?

[HaoYang670]

The timeout could work. But we don't want to set the timeout of dangling sessions same as the normal sessions.

What I want is that if a session can check whether the Kyuubi engine exists every once in a while. Is there a config such as kyuubi.session.check.engine.exists.interval?

[yaooqinn]

kyuubi.session.engine.alive.probe.enabled

I have tried to set this property. But the session are not removed after I delete the cluster and wait for about 10 minutes

Besides, I don't find a property to set the timeout of a session when the engine has been removed

Do I miss something?
