zookeeper節點啟動失敗
環境:zookeeper版本號:3.4.6,三個節點。
有一臺伺服器重啟了,用zkServer.sh start 啟動是出錯,資訊如下:

解決方法:
1. 在配置檔案/usr/local/zookeeper-3.4.6/conf/zoo.cfg ,找到下面兩個配置的值
dataDir=/data/zookeeper_data
dataLogDir=/data/logs/zookeeper
2. 刪除兩個目錄:
/data/zookeeper_data/version-2
/data/logs/zookeeper/version-2
3.重新啟動:zkServer.sh start
