Configuration in Elasticsearch 2

Elastic Stack Elasticsearch
#1

I have 3 elasticsearch nodes (running 1.1.1 version) and the following configuration.

index.number_of_shards: 3
index.number_of_replicas: 2

I am upgrading to Elasticsearch 2.0.
In elasticsearch.yml in 2.0, I did not see any values for default number of shards and replicas. Are these still allowed in 2.0?

#2

Yes, they're still valid. The documentation is the authoritative reference for this.

https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules.html

The elasticsearch.yml that ships with ES doesn't contain all valid configuration parameters.

#3

In an ideal world it should though, so please feel free to raise an issue to get it added (either in the file or in the docs).
