Sahil Takiar commented on HIVE-20519:
-------------------------------------
Another issue that needs to be fixed with this feature is that we should
support closing a SparkSession while it is being opened. The old code was
capable of doing that. Supporting this is important for query cancellation,
especially on a busy cluster where it might take a while to start the Spark
driver.
> Remove 30m min value for hive.spark.session.timeout

> In HIVE-14162 we added the config \{{hive.spark.session.timeout}} which
> provided a way to time out Spark sessions that are active for a long period
> of time. The config has a lower bound of 30m which we should remove. It
> should be possible for users to configure this value so the HoS session is
> closed as soon as the query is complete.
