> My understanding is as follows:
> Hive-on-MR when the cluster is full will wait for resources to be available
> before submitting a job. This is because the hadoop jar command is the
> primary mechanism Hive uses to know if a job is complete or failed.
>
> Hive-on-Spark will timeout after {{SPARK_RPC_CLIENT_CONNECT_TIMEOUT}} because
> the RPC client in the AppMaster doesn't connect back to the RPC Server in
> HS2.
> This is a behavior difference it'd be great to close.
