java - hbase 独立快速启动失败可通过 maven 项目重复

Question

我必须向私有(private) hadoop 集群启动一个 hbase 进程，并且需要简单地演示最低限度的功能；演示不需要安装 hadoop。按照 QuickStart apache hbase 文档通过 shell 失败，我已经能够使用自包含的 maven 项目复制失败。 /etc/hosts 不是问题。

我找到了一个 maven 项目，它似乎是为 deomnstrate 这个相同的功能而构建的，并更新了 deps。

该项目在这里:hbase-demo

要重复我的结果需要 shell 和安装了 maven 的两行:

git clone https://github.com/jnorthrup/hbase-demo
cd hbase-demo

$ mvn clean package exec:java

如果您能帮助恢复此演示代码，我们将不胜感激。摆弄 hbase-site.xml 对独立的 zookeeper 失败没有明显的影响，无论是 shell 还是 maven..

谢谢

Answer 1

更改 hbase-site.xml 以指向您的 hbase 服务器:

<property>
    <name>hbase.rootdir</name>
    <value>hdfs://<hbase machine name>:8020/hbase</value>
</property>

<property>
    <name>hbase.zookeeper.quorum</name>
    <value><zookeeper machine name></value>
</property>
