最佳答案
原因 #1:来自 Handling AWS Service Errors :
A yellow cluster status means that the primary shards for all indices are allocated to nodes in a cluster, but the replica shards for at least one index are not. Single-node clusters always initialize with a yellow cluster status because there is no other node that Amazon ES can assign a replica to. To achieve green cluster status, increase your node count. For more information, see Configuring Amazon ES Domains in this guide and Update Indices Settings in the Elasticsearch documentation.
原因#2:
If you have Kibana installed, it is probably because there is a replica shard for the .kibana index. If you remove that replica shard, your cluster will turn green.
