-------------------------------------
Summary: Simplify default timeout configuration
Key: FLINK-16867
URL: https://issues.apache.org/jira/browse/FLINK-16867
Project: Flink
Issue Type: Improvement
Components: Runtime / Configuration, Runtime / Coordination
Affects Versions: 1.10.0, 1.9.2, 1.11.0
Reporter: Till Rohrmann
Fix For: 1.11.0
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 been explicitly configured. This
has the benefits that the user only need to know about a single timeout value
which is applied cluster wide.
