Amazon OpenSearch Yellow Cluster

• outline

Reason that health of OpenSearch is yellow

• cause

Using only one data node keeps yellow cluster state, if you want to go green, you need more than two date nodes.

• note

Adding data node charges more, so if you are using OpenSearch as test then ignore yellow cluster state.
