不能使用sqlline连接菲尼克斯和Hbase

Question

在伪分布式设置中，我使用Hbase 1.2.6、凤凰-4.13.1-HBASE-1.2、Hadoop2.9.0。我可以在hbase shell中创建表，我希望使用菲尼克斯来读取这些表。运行'sqlline.py localhost:2181:/hbase-不安全‘时，我得到以下错误：

任何帮助都将不胜感激！

更新：我检查了我的动物园管理员文件，清理了所有的文件，并重新启动了动物园管理员和Hbase。reqd文件是创建的，我可以使用'./sqlline.py localhost‘将凤凰连接到hbase。

这个问题是非常清楚的。您的hbase动物园管理员znode是/hbase，而您试图通过/hbase连接菲尼克斯-不安全。

我也面临着同样的问题。在没有kerberos的HDP2.6中，hbase的znode是/hbase-不安全的。所以我在连接jdbc:菲尼克斯:myhost时遇到了同样的错误，它使用默认的znode(/hbase)

希望我的帖子能为像我这样的人节省半个小时。

PS: jdbc字符串中的端口是用于动物园管理员的。所以，不要像我一样愚蠢地使用8765(凤凰端口)。
