SLIDER-174 HBase Master needs data locality
> HBase Master needs data locality
> --------------------------------
>
> Key: SLIDER-174
> URL: https://issues.apache.org/jira/browse/SLIDER-174
> Project: Slider
> Issue Type: Task
> Reporter: Ted Yu
> Assignee: Ted Yu
>
> Currently:
> {code}
> // Master doesn't need data locality
> ROLES.add(new ProviderRole(HBaseKeys.ROLE_MASTER,
> KEY_MASTER,PlacementPolicy.NO_DATA_LOCALITY));
> {code}
> But in RoleHistory#findNodeForNewInstance():
> {code}
> if (role.getNoDataLocality()) {
> return null;
> }
> {code}
> This implies that HBase master instances might be scheduled on one host,
> obviating the goal for HA.
