> Some corner case during HA master switching?
> --------------------------------------------
>
> Key: SPARK-1086
> URL: https://issues.apache.org/jira/browse/SPARK-1086
> Project: Spark
> Issue Type: Bug
> Components: Deploy
> Affects Versions: 0.9.0
> Reporter: Raymond Valencia
>
> In spark standalone HA mode.
> It seems to me that when current master is down, and the new master is not
> elected yet, at this time if the worker is sending executor update or driver
> update message. this message will be lost. Though executor status is rebuild
> after new master is recovered, thus the status might be alright. While the
> driver might be relaunched even it actually finished successfully, this might
> be a problem? And then the message send to AppClientListener might be lost
> and never been regenerated thus lead to some problem?
