> ... > Why it's needed - driver start takes about 20-30s and we want to keep it 5-10 minutes in idle state to prevent this time overhead for kyuubi users in each separate request. Sorry, I'm not a native engine speaker and am not very clear w/ your origin question, for my understanding, I guess you may worry about one of the following ones 1. the `spark-submit` take a long period and kyuubi will treat the launch operation as failed when the launching time reaches the threshold. In this case, you can enlarge `kyuubi.session.engine.initialize.timeout` whose default value is `PT3M` 2. the `spark-submit` is a kind of heavy operation, and you want to keep the started engine alive for a period e.g(10min) even if it does not hold the active connection so that the following connection can reuse the engine. In this case, you can refer to my first reply to learn about "engine share level" -- This is an automated message from the Apache Git Service.
