我正试图按照下面的文章设置hadoopha。
http://hashprompt.blogspot.in/2015/01/fully-distributed-hadoop-cluster.html
配置之后，当我尝试运行

hdfs zkfc -formatZK

我得到以下错误。

Please check the configured value for ha.zookeeper.quorum and ensure that ZooKeeper is running.

在zookeeper安装之后http://rajsyrus.blogspot.sg/2014/04/configuring-hadoop-high-availability.html)，我用

./zkServer.sh start

但是当我看到它的状态时

./zkServer.sh status

结果如下

JMX enabled by default
Using config: /home/huser/zookeeper-3.4.6/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.

这意味着它可能运行不正常。

任何指向错误解决方法的指针都会有很大帮助。
你好，subhankar

在做了拉杰什在回答中提到的事情之后，它似乎起了作用，因为没有任何错误。但是，在安装之后，运行pi示例会显示以下错误。

看起来数据节点没有运行！！任何关于什么可能是错误的指针！

在几次重试之后，我停止了所有操作并重新启动了所有节点。但现在看来namenode02还没有开始。当我运行命令hdfs haadmin-getservicestate nn02时，我得到一个错误操作失败：从mo-4594ddc63/10.97.155.65调用mo-6dd5bf8b8失败，连接异常：java.net.connectexception：连接被拒绝；有关更多详细信息，请参见：wiki.apache.org/hadoop/connectiondensed namenode02中未连接的日志。

在zoo.cfg中更改：

server.1=mo-4594ddc63.mo.sap.corp:2888:3888
server.2=mo-6dd5bf8b8.mo.sap.corp:2888:3888
server.3=mo-e7b2822cb.mo.sap.corp:2888:3888

到

server.1=mo-4594ddc63.mo.sap.corp:2888:3888
server.2=mo-6dd5bf8b8.mo.sap.corp:2889:3889
server.3=mo-e7b2822cb.mo.sap.corp:2890:3890

现在启动zookeeper并检查状态。
