问题
I am new to hadoop, hdfs.. I have do the next steps:
I have started zookeeper in the three namenodes:
*vagrant@172:~$ zkServer.sh start
I can see the status:
*vagrant@172:~$ zkServer.sh status
Result Status:
JMX enabled by default
Using config: /opt/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: follower
with jps command only appear jps and sometimes appear quaroom too:
*vagrant@172:~$ jps
2237 Jps
When I run the next command.
* vagrant@172:~$ hdfs zkfc -formatZK

Any help for this error would be a great help for me.

回答1:
In file hdfs-site.xml:
*I have change all the IPs for the name of the machine. Example: 172.16.8.191 --> machine_Name1
Then in file etc/hosts:
*I have add all the IPs with their respective names
And now it is working perfectly.
