> Key: KUDU-1715
> URL: https://issues.apache.org/jira/browse/KUDU-1715
> Project: Kudu
> Issue Type: Sub-task
> Components: client
> Affects Versions: 1.0.0
> Reporter: David Alves
> Assignee: Jean-Daniel Cryans
>
> On the C++ client we're able to set a ReplicaSelection policy on the
> KuduScanner that hints at which replica should be chosen to perform the scan:
> {code}
> Status SetSelection(KuduClient::ReplicaSelection selection)
> {code}
> ... where ReplicaSelection can have the following values:
> {code}
> LEADER_ONLY, ///< Select the LEADER replica.
> CLOSEST_REPLICA, ///< Select the closest replica to the client,
> ///< or a random one if all replicas are equidistant.
> FIRST_REPLICA ///< Select the first replica in the list.
> {code}
> Having the same functionality in the java client will increase our confidence
> in our tests that use and would be helpful for perf, since it's pretty common
> for leaders to get clustered and the java client only scans from the leader
> currently.
