Startin HBase Shell - Zookeeper 存在但失败答案

【问题标题】：Startin HBase Shell - Zookeeper exists but failsStartin HBase Shell - Zookeeper 存在但失败
【发布时间】：2016-03-08 02:09:36
【问题描述】：

我正在尝试在 Ubuntu 上运行 HBase。我已经安装它并且可以启动它（它会引发一些警告，因为我使用的是 64 位系统，但我被告知我可以忽略这些）。但是，当我尝试启动 shell 时，我收到下面的错误消息，但我是新手，所以很难弄清楚。它说 Zookeeper 存在但失败了 4 次 - 你知道为什么吗？

【问题讨论】：

标签： linux hadoop hbase apache-zookeeper

【解决方案1】：

此问题可能是由以下一个或所有问题引起的：

hbase-site.xml 中的配置问题：在您选择的编辑器中打开 hbase-site.xml 并确保正确设置了以下属性（假设您设置了 HDFS 并在其中创建了 /hbase 目录） ,

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://localhost:9000/hbase</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.clientPort</name>
    <value>2182</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/usr/local/var/zookeeper</value>
  </property>
  <property>
    <name>hbase.master</name>
    <value>localhost:60000</value>
    <description>The host and port that the HBase master runs at.</description>
  </property>
</configuration>

如果您使用本地目录作为 hbase.rootdir，请将 hdfs://localhost:9000/hbase 替换为 file:///${hbase.rootdir}。

hbase-env.sh 中的配置问题：在您选择的文本编辑器中打开 hbase-env.sh 并从
中删除 # 标签
导出 HBASE_MANAGES_ZK=true
Zookeeper服务器未启动：进入zookeeper目录启动zookeeper，在终端执行以下命令，

bin/zkServer 启动

最后，更新完这些配置后重启 hbase。

【讨论】：

这对我特别有用，因为我在本地运行它，所以我不得不用文件更改 hdfs 协议，hbase 开始工作。端口更改也有效，因为主 zkServer 使用 2181，所以我们必须将客户端端口更改为 2182。谢谢。
感谢您节省我的时间@Teddy Belay

【解决方案2】：

先手动启动 Zookeeper：

cd /usr/lib/zookeeper/zookeeper-3.3.6
bin/zkServer.sh start

那就开始Hbase:

start-hbase.sh

在此之前，您必须为 Zookeeper 文件夹提供必要的权限。

【解决方案3】：

我遇到了同样的问题，这是我的解决方案：

首先你需要启动你的habse服务器，然后你可以启动你的hbase shell。

leiline@master:/usr/local/hbase/hbase-1.2.6/bin$ sh start-hbase.sh

leiline@master:/usr/local/hbase/hbase-1.2.6/bin$ hbase shell
