A user reported that enrich indices were not being allocated because of the following incompatible objectives:

1. The system requirement to have an enrich shard replica on every node
2. The user choice to have >1 node per host
3. The user choice to not allocate same replica shards to the same host via cluster.routing.allocation.same_shard.host

While the enrich indices were not fulfilling their objective to have a replica on every node the system is functional and there is good locality of data (each host has a copy) but the cluster state is permanently yellow. This is an annoyance from a monitoring perspective.
