Peter Vary commented on HIVE-17362:
-----------------------------------

I will be honest with you [~leftylev]: I am a developer, so it might be better if someone
more user oriented decides on this :) Where would a user look for this info? The *hive.prewarm.spark.timeout*
does not effect Tez. It only effects Spark, but the other prewarm parameters are used by both.
What do you recommend? I would happy to do it :)

> When using HIVE_PREWARM_ENABLED, we are waiting MAX_PREWARM_TIME for the containers to
warm up. This is currently set to 5s. This is often not enough for a spark session to initialize
the executors. We should be able to configure this, so we can set a value which has an effect.
