@nik9000 Ok, thanks Nik. So I have deleted the old index completely after reindexing my data to a new index. The only changes made to my new index are field type changes from "long" to "int". A new issue I am now facing is that now I am unable to send the new data to the new index ??? I am able to see that the data has reindexed successfully, but when attempting to send new data, Elasticsearch does not seem to pick it up. I have checked for error logs in logs from a Logstash "indexer" which I use to index data from Redis to ES, and there is no mapper exceptions or anything of that nature. The new index and the old both containe(d) the same alias, so the new data should appear in the alias, but it is not. I have also tried creating the index pattern in Kibana (Even though the alias should contin the index), but as expected, still no data. Any ideas? TIA
UPDATE: Even weirder, I see that the index I have deleted reappears after deletion. I have deleted about 3 times already, it seems to be "deleted" for about 20-30 minutes, then reappears in Elasticsearch. I must also mention that I am deleting the index from my master node. Any ideas? TIA
ANOTHER UPDATE: Furthermore, it seems that the old index is created when I trigger the logs that are sent to this particular index. However, in my new template for my new index, I have obviously given the new index name as the new index name value for the "template" field in the template.
