[jira] [Resolved] (FLINK-13500) RestClusterClient requires S3 access when HA is configured

>                 Key: FLINK-13500
>                 URL: https://issues.apache.org/jira/browse/FLINK-13500
>             Project: Flink
>          Issue Type: Bug
>          Components: Runtime / Coordination, Runtime / REST
>    Affects Versions: 1.8.1
>            Reporter: David Judd
>            Priority: Major
>
> RestClusterClient initialization calls ClusterClient initialization, which calls
> org.apache.flink.runtime.highavailability.HighAvailabilityServicesUtils.createHighAvailabilityServices
> In turn, createHighAvailabilityServices calls BlobUtils.createBlobStoreFromConfig, which in our case tries to talk to S3.
> It seems very surprising to me that (a) RestClusterClient needs any form of access other than to the REST API, and (b) that client initialization would attempt a write as a side effect. I do not see either of these surprising facts described in the documentation–are they intentional?
