Commit c8baa0cf1141c792a8535f564b48a2b9c3393d7b in kudu's branch
refs/heads/master from Gabriella Lotz
[ https://gitbox.apache.org/repos/asf?p=kudu.git;h=c8baa0cf1 ]
KUDU-3729 Prefer follower moves in auto-rebalancing
Add --auto_rebalancing_prefer_follower_replica_moves (default: true).
When multiple tables are equally imbalanced, the greedy algorithm
prefers a move whose source server hosts a follower replica for that
table. If no such candidate exists among the ties, it falls back to
a leader-sourced move. When false, equal-skew ties are broken as
before with no leader/follower distinction.
