Can you replace the mutable iterator and while loop with the following?

for (RoutingNode rNode : routingNodes) { ... }

Can you expand a bit here? For example, what is the heuristic being used here? Doesn't need to be super detailed, just a high level description of exactly what is being done.

Nitpick, but can probably just do:

unassignedShardMap.get(index).addShard(shard);

Seems related since the flag is forcefully turned on for SEARCHABLE_SNAPSHOT -

Tests with failures:
 - org.opensearch.backwards.MixedClusterClientYamlTestSuiteIT.test {p0=snapshot.restore/10_basic/Create a snapshot and then restore it}

+        int totalPrimaryShard = 0;
+        for (RoutingNode node : nodeList) {
+            int totalPrimaryPerNode = 0;


What's the difference between totalPrimaryShard above and totalPrimaryPerNode? If the latter conveys totalPrimaryShardPerNode, we can rename it accordingly. If not, maybe a better variable name to distinguish would help here?

Renamed. It was exactly what you figured out.
Simplified the logic and extracted it out.

Can we extract this logic to a different method?

Can we break this down to smaller methods? Looks difficult to follow.
