配置zookeeper，出现诸多如下错误：

Error contacting service. It is probably not running.
    
    
    could not find or load main class org.apache.zookeeper.server.quorum.quorump
    
    JMX enabled by default
    Using config:/home/hadoop/app/zookeeper-3.5.5/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED

找了不少教程，真是修复的心累：

有说JDK问题的，那就检查版本呗；

有说2181端口占用问题的，那就检查端口占用呗；

有说删除pid文件的；

有说删除dataDir=/zookeeperData目录下除myid之外的所有文件，启动zookeeper的；

…

发现相同的问题，很可能造成的原因各不相同，自然也就没法参考。逐个尝试，最后发现是源头出了错——也就是下载的安装文件问题。

下载地址如下：

外网论坛有个人给了答案：

试着下载其中的 .bin.tar.gz ，重新安装，终于没有问题了。
