Description
Greedy planner is not placing equivalent index on an empty indexer node.
Steps to reproduce:-
- Create 5 indexes with 2 replicas so that all the index nodes have equal no. of replicas
- Drop all the replica instance from on index node (10.112.205.102) to make skewed index node.
- Add an index (equivalent index) with one replica
- one replica would go to skewed indexer node and other to one of the two indexer node.
Index replicas are created on non-skewed indexer node, ignoring empty indexer node.
