More specifically:\r\n\r\n1. Moved the access of `StreamThread` in `StreamPartitionAssignor` to `TaskManager`, removed any fields stored in `StreamThread` such as `processId` and `clientId` that are only to be used in `StreamPartitionAssignor`, and pass them to `TaskManager` if necessary.\r\n2. Moved any in-memory states, `metadataWithInternalTopics`, `partitionsByHostState`, `standbyTasks`, `activeTasks` to `TaskManager` so that `StreamPartitionAssignor` becomes a stateless thin layer that access TaskManager directly.\r\n3. Remove the reference of `StreamPartitionAssignor` in `StreamThread`, instead consolidate all related functionalities such as `cachedTasksIds ` in `TaskManager` which could be retrieved by the `StreamThread` and the `StreamPartitionAssignor` directly.\r\n4. Finally, removed the two interfaces used for `StreamThread` and `StreamPartitionAssignor`.\r\n\r\n5. Some minor fixes on logPrefixes, etc.\r\n\r\nFuture work: when replacing the StreamsKafkaClient, we would let `StreamPartitionAssignor` to retrieve it from `TaskManager` directly, and also its closing call do not need to be called (`KafkaStreams` will be responsible for closing it).\r\n\r\n### Committer Checklist (excluded from commit message)\r\n- [ ] Verify design and implementation \r\n- [ ] Verify test coverage and CI build status\r\n- [ ] Verify documentation (including upgrade notes)\r\n","created_at":"2017-11-16T00:16:42Z","updated_at":"2017-11-21T11:44:56Z","closed_at":null,"merged_at":null,"merge_commit_sha":"90f7704d59e83b96d52cf8ee7f634e4c68d8443a","assignee":null,"assignees":[],"requested_reviewers":[],"milestone":null,"commits_url":"https://api.github.com/repos/apache/kafka/pulls/4224/commits","review_comments_url":"https://api.github.com/repos/apache/kafka/pulls/4224/comments","review_comment_url":"https://api.github.com/repos/apache/kafka/pulls/comments{/number}","comments_url":"https://api.github.com/repos/apache/kafka/issues/4224/comments","statuses_url":"https://api.github.com/repos/apache/kafka/statuses/a18b4d59bfca381372b2154ebffffda694b6a562","head":{"label":"guozhangwang:K6170-refactor-assignor","ref":"K6170-refactor-assignor","sha":"a18b4d59bfca381372b2154ebffffda694b6a562","user":{"login":"guozhangwang","id":10729597,"avatar_url":"https://avatars0.githubusercontent.com/u/10729597?v=4","gravatar_id":"","url":"https://api.github.com/users/guozhangwang","html_url":"https://github.com/guozhangwang","followers_url":"https://api.github.com/users/guozhangwang/followers","following_url":"https://api.github.com/users/guozhangwang/following{/other_user}","gists_url":"https://api.github.com/users/guozhangwang/gists{/gist_id}","starred_url":"https://api.github.com/users/guozhangwang/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/guozhangwang/subscriptions","organizations_url":"https://api.github.com/users/guozhangwang/orgs","repos_url":"https://api.github.com/users/guozhangwang/repos","events_url":"https://api.github.com/users/guozhangwang/events{/privacy}","received_events_url":"https://api.github.com/users/guozhangwang/received_events","type":"User","site_admin":false},"repo":{"id":39164613,"name":"kafka","full_name":"guozhangwang/kafka","owner":{"login":"guozhangwang","id":10729597,"avatar_url":"https://avatars0.githubusercontent.com/u/10729597?v=4","gravatar_id":"","url":"https://api.github.com/users/guozhangwang","html_url":"https://github.com/guozhangwang","followers_url":"https://api.github.com/users/guozhangwang/followers","following_url":"https://api.github.com/users/guozhangwang/following{/other_user}","gists_url":"https://api.github.com/users/guozhangwang/gists{/gist_id}","starred_url":"https://api.github.com/users/guozhangwang/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/guozhangwang/subscriptions","organizations_url":"https://api.github.com/users/guozhangwang/orgs","repos_url":"https://api.github.com/users/guozhangwang/repos","events_url":"https://api.github.com/users/guozhangwang/events{/privacy}","received_events_url":"https://api.github.com/users/guozhangwang/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/guozhangwang/kafka","description":"Mirror
