hadoop - HBase 错误 : zookeeper. znode.parent 不匹配

Question

我正在尝试学习 Hadoop，并且我已经达到了 Hadoop 权威指南中的 HBase 部分。我试图启动 HBase 但出现错误。有人可以给我分步指南吗？

opel@ubuntu:~$ zkServer.sh start
JMX enabled by default
Using config: /home/opel/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
opel@ubuntu:~$ start-hbase.sh

opel@ubuntu:~$ hbase shell

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'

有什么问题吗？

Answer 1

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):

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

但这仅适用于独立模式。我仍然不知道如何在使用外部 ZooKeeper 时解决这个问题。
