Re: Elastic scaling with HA (zookeeper)

Hi, Shubham Which Flink version are you using? AFAIK, the JobManager will recover the job from the HA store first, and it won't submit the same job (identify be jobID) again if it has already been recovered. Best, Weihua On Tue, May 2, 2023 at 8:02 PM Shubham Bansal wrote: > Hello everyone, >

Hi DEROCCO, I think you can check the startup command of the job on k8s to see if the jar file is in the classpath. If your job is DataStream, you need to add hadoop azure dependency in your project, and if it is an SQL job, you need to include this jar file in your Flink release package. Or you

Hi chris, I think there is no existing method that allows you to customize placing the operator on the specified node. By the way, I think "predicting the optimal parallelism" of flink jobs is interesting. Currently flink supports autoscaling mechanism, you can find detailed information in this F

Hi Chris, You should be able to do this using nodeSelector, or taints and tolerations. https://github.com/apache/flink-kubernetes-operator/blob/main/helm/flink-kubernetes-operator/templates/flink-operator.yaml#L55:L61 Thanks John On Fri, May 5, 2023 at 8:38 AM wrote: > Hi, > > is there a way

Custom Operator Placement for Kubernetes

2023-05-05 Thread chris-weiland
Hi,   is there a way to manually define which node an operator should be placed in, using Kubernetes?   To give a bit more context, for my master's thesis, I'm looking into predicting the optimal parallelism degree for a node. To do so, we use a Zero Shot Model, which predicts the latency and t
