[jira] [Comment Edited] (HELIX-214) User-defined rebalancer should never use SEMI_AUTO code paths

Attached the patch. Previously, even the user-defined rebalancer would use the old ideal state calculator initially and then get invoked for the rebalance stage. This is no longer the case, as the partitions are initialized, but a mapping is not computed until the user-defined rebalancer is first run.

> The user-defined rebalancer should always return the full mapping, and should be able to do this from the start, and not after an initial balance
