1.自行修改server.properties中broker id後造成與meta.properties中資料不匹配

kafka.common.InconsistentBrokerIdException: Configured broker.id 2 doesn’t match stored broker.id 1 in meta.properties. If you moved your data, make sure your configured broker.id matches. If you intend to create a new broker, you should remove all data in your data directories (log.dirs).

2.__consumer_offsets這個topic是由kafka自動建立的，預設49個，這個topic是不能被刪除的！

Error while executing topic command : Topic __consumer_offsets is a kafka internal topic and is not allowed to be marked for deletion.

為什麼這裡會是這樣儲存__consumer_offsets的呢：

• [1.] 將所有 N Broker 和待分配的 i 個 Partition 排序
• [2.] 將第 i 個 Partition 分配到第(i mod n)個 Broker 上

3.刪除topic時

Topic frist is already marked for deletion.

徹底刪除topic：

• [1. ] 刪除Topic，delete.topic.enable=true這裡要設定為true
• [2. ] 刪除log日誌
• [3. ] 刪除ZK中的Topic記錄

當然，這裡是你delete.topic.enable設定為false時Zookeeper下才會有這個節點
