Till Rohrmann commented on FLINK-13750:
---------------------------------------
This sounds good to me.
Maybe another thought. We could split {{HighAvailabilityServices}} up into
{{ClientHighAvailabilityServices}} and {{ClusterHighAvailabilityServices}} and
let {{HighAvailabilityServices}} extend both interfaces. That way we would
decompose the original interface into smaller ones which could be passed into
the respective using components {{ClientHighAvailabilityServices}} go into the
{{ClusterClient}}, whereas {{ClusterHighAvailabilityServices}} go into the
cluster components.
This would, however, break binary backwards compatibility and people would need
to recompile their custom implementations against the updated interface, I
guess.

> Project: Flink
> Issue Type: Improvement
> Components: Command Line Client, Runtime / Coordination
> Reporter: Chesnay Schepler
> Assignee: TisonKun
> Priority: Major
>
> Currently, we use the same {{HighAvailabilityServices}} on the client and
> server. However, the client does not need several of the features that the
> services currently provide (access to the blobstore or checkpoint metadata).
> Additionally, due to how these services are setup they also require the
> client to have access to the blob storage, despite it never actually being
> used, which can cause issues, like FLINK-13500.
> [~Tison] Would be be interested in this issue?
