Zookeeper之Error contacting service. It is probably not running.
安裝ZooKeeper時,無論是修改zoo.cfg;還是myid,都檢查了幾遍都沒有錯誤。但是開啟Zookeeper服務時出現:
Error contacting service. It is probably not running.
後來查看日誌發現,是我的hosts文件,之前手誤出錯了,變成了27.0.0.1
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
