,我得到以下错误:

我试图搜索类似的错误,但到目前为止还没有找到解决方案
有人有处理这个问题的经验吗?请帮帮我
此外,我的hbase-site.xml如下所示
> <configuration> <property>
> <name>hbase.rootdir</name>
> <value>hdfs://localhost:54310/hbase</value>
> </property>
> <property>
> <name>hbase.zookeeper.property.dataDir</name>
> <value>/home/hduser/zookeeper</value>
> <description>Property from ZooKeeper's config zoo.cfg.
> The directory where the snapshot is stored.

> </property> </configuration>
谢谢请查找更多关于您错误的参考资料,以防您遗漏。快乐编码:)谢谢您的帮助。我已经看过你的链接,但还没有找到解决我的问题的办法。我可以在Hbase外壳中运行良好,但不能在Eclipse的Java中运行程序,它总是显示该异常
