Hai Zhou resolved RATIS-2684.
-----------------------------
Resolution: Won't Fix
> Add first-class config and docs for Ratis raft.server.close.threshold
> ----------------------------------------------------------------------
>
> Key: RATIS-2684
> URL: https://issues.apache.org/jira/browse/RATIS-2684
> Project: Ratis
> Issue Type: Improvement
> Reporter: Hai Zhou
> Priority: Major
>
> `raft.server.close.threshold` (default 60s) controls when the Ratis
> `JvmPauseMonitor`
> shuts down the local raft server after a JVM/host pause, but in Celeborn
> this knob is
> effectively invisible: there is no dedicated `CelebornConf` entry
> (unlike other Ratis
> params such as `celeborn.master.ha.ratis.raft.rpc.request.timeout`), and
> the only way to
> tune it is the undocumented `celeborn.ratis.*` passthrough
> (`celeborn.ratis.raft.server.close.threshold=180s`), discoverable only
> by reading the
> source. No doc mentions that a long JVM pause makes a master leave its
> raft group until
> the process restarts.
