HBase standalone无法连接（无法创建表）

Question

我试图在独立模式下部署Hbase以下这篇文章：http://hbase.apache.org/book.html#quickstart.版本是0.92.1-cdh4.1.2

但我得到这些错误时，试图创建一个表：

错误消息：

    13/04/01 14:07:10 ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists failed after 3 retries
13/04/01 14:07:10 WARN zookeeper.ZKUtil: hconnection Unable to set watcher on znode /hbase/master

    at org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.<init>(HConnectionManager.java:569)

输出日志：

我的配置：

>

在hbase env中添加了JAVA_HOME。上海

hbase_网站。xml

<name>hbase.rootdir</name>

<value>file:///home/hadoop/data</value>

<name>hbase.zookeeper.property.dataDir</name>

<value>file:///home/hadoop/zookeeper</value>

我试图修改/etc/hosts，它看起来像这样（oracle是主机名）：

127.0.0.1   localhost oracle

或者

[server ip]   localhost oracle

但这些对我不起作用。

我的确切密码是：

[usr@oracle bin]$ ./start-hbase.sh 
starting master, logging to /home/hadoop/hbase-0.94.6/bin/../logs/hbase-usr-master-oracle.out
[usr@oracle bin]$ hbase shell

Version 0.92.1-cdh4.1.2, rUnknown, Thu Nov  1 18:02:07 PDT 2012

提前谢谢！

Answer 1

在HBase 1.2.3中，我在独立模式下遇到了几乎相同的错误“ZooKeeper存在在4次重试后失败”。这是由运行./start-hbase.sh而没有连接到端口2181的权限引起的。解决方案非常简单：

sudo ./start-hbase.sh

以防万一，hbase站点的配置。xml是：

<configuration>
   <property>
      <name>hbase.rootdir</name>
      <value>file:///home/hadoop/HBase/HFiles</value>
   </property>
   <property>
      <name>hbase.zookeeper.property.dataDir</name>
      <value>/home/hadoop/zookeeper</value>
   </property>
</configuration>

我不确定你是否在Mac上，但我也有这个问题。原来是因为。DS_存储文件位于根区域服务器的文件夹中，导致连接异常。真奇怪！

Answer 3

看起来你缺少了hbase。动物园管理员。quorum在您的配置中。请查看本HBase指南章节，它可能会有帮助：http://hbase.apache.org/book/zookeeper.html

另外，请检查zookeeper是否在正确的端口启动，以及（更常见的情况）正确的IP接口。
