If you set the below curl command with only 1 index node you are not able to create index.

curl -u Administrator:password localhost:9102/settings -d "{\"indexer.settings.num_replica\":1}"

We should put note stating when you set this cluster wide setting you must ensure you have at least 2 index nodes.
