[jira] [Commented] (FLINK-13417) Bump Zookeeper to 3.5.5
[ https://issues.apache.org/jira/browse/FLINK-13417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16967103#comment-16967103 ] David Judd commented on FLINK-13417: Flagging interest in this because ZK 3.5 also contains a fix for https://issues.apache.org/jira/browse/ZOOKEEPER-1576 - which we're running into & has the effect that (since we provide hostnames instead of IPs currently) the inability to reach a single Zookeeper host from the Flink job manager will bring it, and therefore the Flink cluster, down. > Bump Zookeeper to 3.5.5 > --- > > Key: FLINK-13417 > URL: https://issues.apache.org/jira/browse/FLINK-13417 > Project: Flink > Issue Type: Improvement > Components: Runtime / Coordination >Affects Versions: 1.9.0 >Reporter: Konstantin Knauf >Priority: Major > Fix For: 1.10.0 > > > User might want to secure their Zookeeper connection via SSL. > This requires a Zookeeper version >= 3.5.1.

[jira] [Commented] (FLINK-13500) RestClusterClient requires S3 access when HA is configured
[ https://issues.apache.org/jira/browse/FLINK-13500?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16909071#comment-16909071 ] David Judd commented on FLINK-13500: Ok, that's good to know. Thanks for the followup! This isn't a problem for me in the short term - I just gave the client box the needed permissions. I think it would be useful to describe in the docs though. (Also FWIW I think you linked the wrong ticket.) > 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.
