JavaJDK 1.6 Hadoop ZooKeeper AccumuLo
Hadoop正在启动，似乎运行良好。测试了NameNode和JobTracker，它们都可以在localhost html页面中看到。
ZooKeeper服务器启动正常，但我在客户端shell中收到错误。
你可以在下面看到ZooKeeper和AccumuLo的错误。
原版的
我试图在装载Mountain Lion的OS X上安装这些技术以进行测试。该设置是使用“localhost”的单节点设置。
我遇到了几个问题......
1）运行sudo zkCli - > ls /抛出错误
Exception in thread "main" org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /

2）我尝试运行bin / accumulo init并收到此错误...

我的班级似乎有问题，但我不确定我需要做什么。
以下是AccumuLo编译的摘要：

我知道用于测试目的的最简单方法是为您选择的虚拟机获取Hortonworks Sandbox映像并以此方式运行。它不会让您体验从头开始配置集群的经验，但如果您想从用户角度进行测试，那将是一个很好的开始。

欢迎来到Ask Different。我们有一个如何询问的指南 - 看一下它，看看你是否可以添加一个编辑列出你试图解决它的步骤（以及为什么它不起作用）或者至少让我们确切地知道您安装的Java版本

java -version或您安装第三方软件的软件包。如果你可以稍微缩小选项范围，那么有人帮助的机会就会增加。
@AlanShutko - 你应该把它作为一个真正的答案。卸载所有修补，依赖等等...对于刚刚开始测试的人来说是一个有效的答案。即使这个OP真的需要弄清楚基本的安装步骤，它也很有可能帮助其他人。
