Rui Li commented on HIVE-12650:
-------------------------------
The timeout is necessary in case the RSC crashes due to some errors. But the
issue here shows that it could also because the RSC is just waiting for
resources from a busy cluster. I think we need a way to distinguish these two
scenarios and don't timeout on the latter.
> Spark-submit is killed when Hive times out. Killing spark-submit doesn't
> cancel AM request. When AM is finally launched, it tries to connect back to
> Hive and gets refused.

> I think hive.spark.client.server.connect.timeout should be set greater than
> spark.yarn.am.waitTime. The default value for
> spark.yarn.am.waitTime is 100s, and the default value for
> hive.spark.client.server.connect.timeout is 90s, which is not good. We can
> increase it to a larger value such as 120s.
