Steven Zhen Wu commented on FLINK-16867:
----------------------------------------

I should clarify that web.timeout becomes irrelevant to us for job submission 
via REST API. It seems that only client.timeout matters for that particular 
code path of submitting job.

> Simplify default timeout configuration

>             Project: Flink
>          Issue Type: Improvement
>          Components: Runtime / Configuration, Runtime / Coordination
>    Affects Versions: 1.9.2, 1.10.0, 1.11.0
>            Reporter: Till Rohrmann
>            Priority: Minor
>             Fix For: 1.12.0

> At the moment, Flink has several timeout options:
> * {{akka.ask.timeout}}: Timeout for intra cluster RPCs (JM <\-> RM <\-> TE)
> * {{web.timeout}}: Timeout for RPCs between REST handlers and RM, JM, TE
> At the moment, these values are separately configured. This requires the user 
> to know about both configuration options and that Flink has multiple timeout 
> values. 
> In order to simplify setups I would suggest that {{web.timeout}} defaults to 
> {{akka.ask.timeout}}, if {{web.timeout}} has not been explicitly configured. 
> This has the benefits that the user only need to know about a single timeout 
> value which is applied cluster wide.
