Removes HostsSniffer.Builder and lets SnifferBuilder create the default HostsSniffer. This simplifies the Sniffer initialization as the HostsSniffer is not mandatory anymore. It can still be specified though in case the configuration needs to be changed or a different impl has to be used.","created_at":"2016-07-26T12:31:41Z","updated_at":"2016-07-26T13:06:59Z","closed_at":null,"merged_at":null,"merge_commit_sha":"0a968b559b2db7e6cbac591f3999a3e38750b3e3","assignee":null,"assignees":[],"milestone":null,"commits_url":"https://api.github.com/repos/elastic/elasticsearch/pulls/19599/commits","review_comments_url":"https://api.github.com/repos/elastic/elasticsearch/pulls/19599/comments","review_comment_url":"https://api.github.com/repos/elastic/elasticsearch/pulls/comments{/number}","comments_url":"https://api.github.com/repos/elastic/elasticsearch/issues/19599/comments","statuses_url":"https://api.github.com/repos/elastic/elasticsearch/statuses/de57795ada5b16007085c6c2f67958c20f0005d4","head":{"label":"javanna:enhancement/sniffer_builder","ref":"enhancement/sniffer_builder","sha":"de57795ada5b16007085c6c2f67958c20f0005d4","user":{"login":"javanna","id":832460,"avatar_url":"https://avatars.githubusercontent.com/u/832460?v=3","gravatar_id":"","url":"https://api.github.com/users/javanna","html_url":"https://github.com/javanna","followers_url":"https://api.github.com/users/javanna/followers","following_url":"https://api.github.com/users/javanna/following{/other_user}","gists_url":"https://api.github.com/users/javanna/gists{/gist_id}","starred_url":"https://api.github.com/users/javanna/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/javanna/subscriptions","organizations_url":"https://api.github.com/users/javanna/orgs","repos_url":"https://api.github.com/users/javanna/repos","events_url":"https://api.github.com/users/javanna/events{/privacy}","received_events_url":"https://api.github.com/users/javanna/received_events","type":"User","site_admin":false},"repo":{"id":6652220,"name":"elasticsearch","full_name":"javanna/elasticsearch","owner":{"login":"javanna","id":832460,"avatar_url":"https://avatars.githubusercontent.com/u/832460?v=3","gravatar_id":"","url":"https://api.github.com/users/javanna","html_url":"https://github.com/javanna","followers_url":"https://api.github.com/users/javanna/followers","following_url":"https://api.github.com/users/javanna/following{/other_user}","gists_url":"https://api.github.com/users/javanna/gists{/gist_id}","starred_url":"https://api.github.com/users/javanna/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/javanna/subscriptions","organizations_url":"https://api.github.com/users/javanna/orgs","repos_url":"https://api.github.com/users/javanna/repos","events_url":"https://api.github.com/users/javanna/events{/privacy}","received_events_url":"https://api.github.com/users/javanna/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/javanna/elasticsearch","description":"Open
