我是新來的Hadoop，HDFS ..我有做下一個步驟：錯誤執行HDFS的NameNode -format
我已經在三個namenodes開始飼養員：
*[email protected]:~$ zkServer.sh start
我可以看到狀態：
*[email protected]:~$ zkServer.sh status
結果狀態：
JMX enabled by default
Using config: /opt/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: follower
與JPS命令只出現JPS，有時出現quaroom太：
*[email protected]:~$ jps
2237 Jps
我運行下一個命令了。
* [email protected]:~$ hdfs zkfc -formatZK
當我執行下，它失敗：
[email protected]:~$ hdfs namenode -format

然後，如果我跑：
*[email protected]:~$ hdfs namenode -bootstrapStandby
我有一個錯誤：

任何對這個錯誤的幫助對我來說都是一個很大的幫助。
我的配置是下一個：
