Apache Spark reassigned SPARK-11726:
------------------------------------
Assignee: Apache Spark
> Legacy Netty-RPC based submission in standalone mode does not work
> ------------------------------------------------------------------
>
> Key: SPARK-11726
> URL: https://issues.apache.org/jira/browse/SPARK-11726
> Project: Spark
> Issue Type: Bug
> Components: Deploy, Spark Submit
> Reporter: Jacek Lewandowski
> Assignee: Apache Spark
>
> When the application is to be submitted in cluster mode and standalone Spark
> scheduler is used either legacy RPC based protocol or REST based protocol can
> be used. Spark submit firstly tries REST and if it fails it tries RPC.
> When Akka based RPC is used, the REST based connection fails immediately
> because Akka rejects non-Akka connection. However in Netty based RPC, the
> REST client seems to wait for the response indefinitely, thus making it
> impossible to fail and try RPC.
> The fix is quite simple - set a timeout on reading response from the server.
