gateway.expected_nodes default should be 0

[jgerry]

gateway.expected_nodes set to 1 causes indexes that are created in a cluster to be deleted, at least for me. This occurred on both 1.7.3 and 2.0.0. According to the documentation, the default should be zero.

This caused me some mild headaches over the past couple of days but the cookbook has been a fantastic help. Thanks!

Thanks @jgerry! I confirmed that it defaults to zero in the source repo as well:
https://github.com/elastic/elasticsearch/blob/v2.0.1/distribution/src/main/resources/config/elasticsearch.yml

It looks like the cookbook has set it to 1 for a long time:
https://github.com/elastic/cookbook-elasticsearch/blob/0.3.x/attributes/default.rb#L86

I concur that the default values are probably best. We'll get this out shortly. Thanks again!

Glad to help! btw the cookbook seems to work fine with 2.1.0 as well, been working on that today. Just adding new sha sums and version attributes, works perfectly.

Thanks @jgerry! Fixing this and the other logging.yml change and will start looking into the ES 2.1.0 support, and then we'll probably push a release 👍
