【问题描述】：

出于测试目的，我正在尝试在装有 Mountain Lion 的 OS X 上安装这些技术。该设置是使用“localhost”的单节点设置。

我遇到了一些问题...

1) 运行 sudo zkCli -> ls / 抛出错误

Exception in thread "main" org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /
    at org.apache.zookeeper.KeeperException.create(KeeperException.java:99)
    at org.apache.zookeeper.KeeperException.create(KeeperException.java:51)

    at org.apache.zookeeper.ZooKeeperMain.run(ZooKeeperMain.java:323)
    at org.apache.zookeeper.ZooKeeperMain.main(ZooKeeperMain.java:282)

2) 我尝试运行 bin/accumulo init 并收到此错误...

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/accumulo/start/Platform
Caused by: java.lang.ClassNotFoundException: org.apache.accumulo.start.Platform

我的班级似乎出了点问题，但我不确定我需要做什么。

这里是 AccumuLo 编译的总结：

标签： hadoop apache-zookeeper accumulo

【解决方案1】：

1) Zookeeper 是否正在运行？

2) 我建议从二进制 tarball 下载运行 Accumulo，而不是自己构建它。如果必须构建它，请使用 mvn package -P assemble。你是从后备箱跑的吗？如果是这样，我们不再从源目录运行 accumulo。在 assemble/target 中查找构建的 tarball，安装并运行它。 accumulo-env.sh 配置正确吗？您是否在 bash 脚本中配置了任何旧的环境变量，设置了错误的 ACCUMULO_HOME？
