Hello there,
I have three node cluster implementation and I have noticed some error when I started elasticsearch for master node.

This is telling me that one of your shards is unavailable, it could be a number of things.
You can try recovering if you have snapshots, otherwise, you need to figure out why that shard isn't coming online. You can try rerouting the shard, or you can check to see if you have `cluster.routing.allocation.enable` set to `all`
try doing `curl -XGET localhost:9200/_cat/shards?h=index,shard,prirep,state,unassigned.reason| grep UNASSIGNED`and posting the results
It will give a reason like `NODE_LEFT` or similar, which will help diagnose the issue further.
This is a good resource to help you move forward: [How to Resolve Unassigned Shards in Elasticsearch | Datadog](https://www.datadoghq.com/blog/elasticsearch-unassigned-shards/)
