Subject [jira] [Commented] (SPARK-11098) RPC message ordering is not guaranteed
Date Wed, 21 Oct 2015 11:26:27 GMT

Shixiong Zhu commented on SPARK-11098:
--------------------------------------

[~vanzin] Vanzin Sorry I didn't realize you were not working on this one...

I just sent a PR to fix the message ordering issue. I think we should guarantee that if using
the same RpcEndpointRef to send multiple messages in the same thread, the receiver side should
see these messages in the same order.

> NettyRpcEnv doesn't guarantee message delivery order since there are multiple threads
sending messages in clientConnectionExecutor thread pool. We should fix that.
