我在 zoo.cfg 中设置： clientPort=2181
cloudera@cloudera-vm:/$ sudo /usr/lib/zookeeper/bin/zkServer.sh start
我收到以下回复：
JMX enabled by default
Using config: /usr/lib/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
cloudera@cloudera-vm:/$ sudo /usr/lib/zookeeper/bin/zkServer.sh 状态
JMX enabled by default
Using config: /usr/lib/zookeeper/bin/../conf/zoo.cfg
Mode: standalone
但
$ echo ruok | nc localhost 2181
$
没有给出任何输出。问题出在哪儿？
