Answer 1

If you are using Magento and getting 'No alive nodes found in your cluster' error while reindexing.

Make sure you have updated following :

1. Your Host and port : '[host]:[port]'. Eg: 'es-node1.fqdn:9200, es-node2.fqdn:9200' or 'localhost:9200' in System -> Configuration -> Elastic Configuration.
2. Update your indices alias name and indices name pattern in admin configuration same as above.

Try this, and clear cache and reindex. It will solve your issue.
