------------------------------------
Assignee: Gabriella Lotz
> Add explicit --avoid_leader_moves flag to CLI rebalancer
> --------------------------------------------------------
>
> Key: KUDU-3760
> URL: https://issues.apache.org/jira/browse/KUDU-3760
> Project: Kudu
> Issue Type: Sub-task
> Reporter: Gabriella Lotz

> Priority: Major

> {*}File{*}:
> {{{}[src/kudu/tools/rebalancer_tool.cc](src/kudu/tools/rebalancer_tool.cc){}}},
> {{IntraLocationRunner}}
> The CLI {{kudu rebalance}} tool now silently gets
> {{prefer_follower_moves=true}} because the constructor default changed
> (because of "avoid leader moves" optimization). Add a
> {{DEFINE_bool(rebalancing_avoid_leader_moves, true, ...)}} flag in the tool
> and plumb it to {{{}TwoDimensionalGreedyAlgo{}}}'s constructor. The default
> should match the new behavior (true) but make it explicit and overridable.
