xiangyu feng updated FLINK-32756:
---------------------------------
Summary: Reuse ClientHighAvailabilityServices when creating
RestClusterClient (was: Reuse ClientHighAvailabilityServices in
RestClusterClient when submitting OLAP jobs)
> Reuse ClientHighAvailabilityServices when creating RestClusterClient
> --------------------------------------------------------------------
>
> Key: FLINK-32756
> URL: https://issues.apache.org/jira/browse/FLINK-32756
> Project: Flink
> Issue Type: Sub-task
> Components: Client / Job Submission
> Reporter: xiangyu feng
> Priority: Major
>
> Currently, every newly built RestClusterClient will create a new
> ClientHighAvailabilityServices which is both unnecessary and resource
> consuming. For example, each ZooKeeperClientHAServices contains a ZKClient
> which holds a connection to ZK server and several related threads.
> By reusing ClientHighAvailabilityServices across multiple RestClusterClient
> instances, we can save system resources(threads, connections), connection
> establish time and leader retrieval time.
