[GitHub] [helix] NealSun96 opened a new issue #1166: Change getBaselineAasignment to account for partial-WAGED clusters
NealSun96 opened a new issue #1166:
URL: https://github.com/apache/helix/issues/1166
WAGED Rebalancer by design only supports one-off migration of resources. As a result, its `getBaselineAssignment()` did not consider the case of a cluster that's partially managed by WAGED. It tries to get baselines for all resources from the cluster; if there's no baseline data, it gets current states for all resources as a fallback. It doesn't care for resources that don't have baseline while other resources have baselines - when that's the case, the resources that don't have baseline will not fallback to their current states; they will simply not have baselines.
The logic is now changed to a per resource level. If a resource has baseline, the baseline will be used; else, the current state will be used.
