问题描述
我正在学习Hadoop，并且我已经在Hadoop权威指南中了解了HBase部分。
我试图启动HBase并出现错误。有人可以给我一步一步的指导吗？

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'
有什么不对吗？
is there anything wrong?
推荐答案
我有同样的问题。对我来说，解决方案是将以下属性添加到 hbase-site.xml （对于我来说，它可以在 / usr / lib / hbase下找到/ conf 目录）：
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>
但这只适用于独立模式。在使用外部ZooKeeper时，我仍然不知道如何解决这个问题。
But this is only for the standalone mode. I still have no idea how to solve this problem when using external ZooKeeper.
