Hi ,  
I am trying to shrink the indices in elasticsearch. Currenrly i have 5 primary shards and 1 replica .  
I want to change it to 1 primary and 1 replica shards.  
i have executed the steps mention in [Shrink Index | Elasticsearch Reference [5.5] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/5.5/indices-shrink-index.html)

But while shrinking i am getting below error. Anyone can help?

curl -XPOST -u xxxx:xxxxx 'xx.xx.xx.xx:9200/reporting-2017.08.12/\_shrink/reporting-2017.08.12-reindexed?pretty' -H 'Content-Type: application/json' -d'

Do you have any index templates that match the new index name (`reporting-2017.08.12-reindexed`)? There's a bug that will be fixed in 5.6 that causes index templates to be applied to the new index ([https://github.com/elastic/elasticsearch/pull/25380](https://github.com/elastic/elasticsearch/pull/25380)).

In the meantime, you could make sure that the new index has a name that would not match the index template.
