Xuefu Zhang commented on HIVE-17362:
------------------------------------
I like the idea of replacing the code trick with the configurations. However,
it seems to me that 4m is a long time. Nevertheless, we probably need to set
{{hive.prewarm.numcontainers}} to whatever number of containers we are
expecting. Otherwise, the test might have to wait for 4m as it will never gets
the default number (10) of containers.
> The MAX_PREWARM_TIME should be configurable on HoS

> 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.
