HBase 错误:zookeeper.znode.parent 不匹配 [英] HBase Error : zookeeper.znode.parent mismatch

问题描述

我正在尝试学习 Hadoop，并且我已经阅读了 Hadoop 权威指南中的 HBase 部分.我尝试启动 HBase 并出错.有人能给我一步一步的指导吗?

有什么问题吗?

解决方案

我遇到了同样的问题.对我来说，解决方案是将以下属性添加到 hbase-site.xml (对我来说，它可以在 /usr/lib/hbase/conf 目录下找到):

<预><代码><配置><财产><name>zookeeper.znode.parent</name><value>/hbase-unsecure</value></属性></配置>

但这仅适用于独立模式.使用外部ZooKeeper时，我仍然不知道如何解决这个问题.

i am trying to learn Hadoop and i'v reached HBase section in Hadoop Definitive Guide. i tried to start HBase and got error. Could someone give me step-by-step guide?

ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 times

Here is some help for this command:
Show cluster status. Can be 'summary', 'simple', or 'detailed'. The
default is 'summary'. Examples:

  hbase> status
  hbase> status 'simple'
  hbase> status 'summary'
  hbase> status 'detailed'

is there anything wrong?

解决方案

I had the same problem. For me the solution was to add the following property to the hbase-site.xml (for me it can be found under /usr/lib/hbase/conf directory):

<configuration>
        <property>
                <name>zookeeper.znode.parent</name>
                <value>/hbase-unsecure</value>
        </property>
</configuration>

But this is only for the standalone mode. I still have no idea how to solve this problem when using external ZooKeeper.
