--------------------------------
Status: In Review (was: Open)
> LA rebalancer tries to amend non-fixable policy violations in case of RF=2
> and three and more locations
> -------------------------------------------------------------------------------------------------------
>
> Key: KUDU-2688
> URL: https://issues.apache.org/jira/browse/KUDU-2688
> Project: Kudu
> Issue Type: Bug
> Components: CLI
> Affects Versions: 1.8.0
> Reporter: Alexey Serbin
> Assignee: Alexey Serbin
> Priority: Major
>
> In case of RF=2 and more than two locations, the logic of the LA rebalancer
> suggests a fix for the distribution of replicas, and the rebalancer loops
> indefinitely trying to implement the suggested replica movements.
> However, RF=2 is a special case: any replica distribution of a tablet with
> RF=2 is a violations of the placement policy constraints and it's impossible
> to fix that, regardless of number of locations in the cluster.
