This happens after an election and somewhat sporadically.  The root issue appears to be that the node in candidate state should return to follower state if it starts receiving heartbeats from a new leader.  The node was not returning to follower state causing it to become inconsistent w/ the cluster.\r\n\r\nIn addition to this fix, when running multiple nodes locally w/ raft tracing, it's very difficult\r\nto determine which node is logging.  This adds the nodes state(leader,follower,candidate) and\r\nid to all the log messages so we can trace the nodes states more easily.\r\n\r\nAlso fixes test output alignment when there is a failure in an integration test.","created_at":"2015-04-24T19:30:07Z","updated_at":"2015-04-24T21:39:54Z","closed_at":null,"merged_at":null,"merge_commit_sha":"71c294c9957e30ce961a522938df51a21260c071","assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/influxdb/influxdb/pulls/2418/commits","review_comments_url":"https://api.github.com/repos/influxdb/influxdb/pulls/2418/comments","review_comment_url":"https://api.github.com/repos/influxdb/influxdb/pulls/comments{/number}","comments_url":"https://api.github.com/repos/influxdb/influxdb/issues/2418/comments","statuses_url":"https://api.github.com/repos/influxdb/influxdb/statuses/49f9f1c708280fbad9884298463fab4be34c9f50","head":{"label":"influxdb:jw-int-tests","ref":"jw-int-tests","sha":"49f9f1c708280fbad9884298463fab4be34c9f50","user":{"login":"influxdb","id":5713248,"avatar_url":"https://avatars.githubusercontent.com/u/5713248?v=3","gravatar_id":"","url":"https://api.github.com/users/influxdb","html_url":"https://github.com/influxdb","followers_url":"https://api.github.com/users/influxdb/followers","following_url":"https://api.github.com/users/influxdb/following{/other_user}","gists_url":"https://api.github.com/users/influxdb/gists{/gist_id}","starred_url":"https://api.github.com/users/influxdb/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/influxdb/subscriptions","organizations_url":"https://api.github.com/users/influxdb/orgs","repos_url":"https://api.github.com/users/influxdb/repos","events_url":"https://api.github.com/users/influxdb/events{/privacy}","received_events_url":"https://api.github.com/users/influxdb/received_events","type":"Organization","site_admin":false},"repo":{"id":13124802,"name":"influxdb","full_name":"influxdb/influxdb","owner":{"login":"influxdb","id":5713248,"avatar_url":"https://avatars.githubusercontent.com/u/5713248?v=3","gravatar_id":"","url":"https://api.github.com/users/influxdb","html_url":"https://github.com/influxdb","followers_url":"https://api.github.com/users/influxdb/followers","following_url":"https://api.github.com/users/influxdb/following{/other_user}","gists_url":"https://api.github.com/users/influxdb/gists{/gist_id}","starred_url":"https://api.github.com/users/influxdb/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/influxdb/subscriptions","organizations_url":"https://api.github.com/users/influxdb/orgs","repos_url":"https://api.github.com/users/influxdb/repos","events_url":"https://api.github.com/users/influxdb/events{/privacy}","received_events_url":"https://api.github.com/users/influxdb/received_events","type":"Organization","site_admin":false},"private":false,"html_url":"https://github.com/influxdb/influxdb","description":"Scalable
