Gabriella Lotz updated KUDU-3761:
---------------------------------
Description:
Cross-location moves via {{LocationBalancingAlgo}} have zero follower
awareness. Fixing this requires:
# Passing {{ts_with_followers_by_table_and_tag}} into
{{{}LocationBalancingAlgo::GetNextMove(){}}}{{{}, as currently it only receives
LocationBalancingInfo{}}}
# Applying the same two-candidate (non-leader vs fallback) pattern as
{{TwoDimensionalGreedyAlgo}}
