Question

我正在尝试在装载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。

我遇到了一些问题......

1）运行sudo zkCli - ＆gt; 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

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：

Answer 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。你是从树干跑吗？如果是这样，我们不再从源目录运行accumulo。在汇编/目标中查找构建的tarball，安装并运行它。 accumulo-env.sh配置正确吗？您是否在bash脚本中配置了旧的环境变量，设置了错误的ACCUMULO_HOME？

在Mac上安装Hadoop，ZooKeeper，AccumuLo
