-------------------------------------
Assignee: Tian Gao
> Restart daemon if the executor can't build a connection with the worker
> -----------------------------------------------------------------------
>
> Key: SPARK-54711
> URL: https://issues.apache.org/jira/browse/SPARK-54711
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 4.2.0
> Reporter: Tian Gao
> Assignee: Tian Gao
> Priority: Major
> Labels: pull-request-available
>
> When the executor asks the daemon to spawn a new worker, the executor tries
> to establish a connection without any timeout mechanism. If the worker has
> some issue and hang before it can establish a connection with the executor,
> the executor will hang there forever.
> We have a timeout mechanism for simple workers, and we should have a similar
> mechanism for daemon based workers.
