Question

连接到hbase我写这段代码：

 Class.forName("com.salesforce.phoenix.jdbc.PhoenixDriver");
           conn = DriverManager.getConnection("jdbc:phoenix:localhost:2181");

但跑完后给我这个错误：

我无法理解这是什么问题。我单独安装hbase 0.94.10和zookeeper 3.4.5，我不确定配置是否正确。您可以指导并帮助我正确配置它们

Answer 1

您是否确保将凤凰服务器jar（其名称为phoenix-.jar，我认为应该是phoenix-2.0.0.jar）复制到您所有的区域服务器？还要确保将phoenix jar的位置附加到HBase类路径。您需要将以下内容放在所有区域服务器的hbase-env.sh中：

HBASE_CLASSPATH=$HBASE_CLASSPATH:/path/to/phoenix-2.0.0.jar

之后您需要重新启动群集。然后凤凰会工作。您还可以阅读他们github project page的安装指南。更新：我刚看到他们更新了他们的文档。最后一个版本的文档更直接，但我认为你会管理......

Answer 2

为仍在寻找的人添加答案：

您的jdbc连接字符串必须如下所示：

JDBC：凤：zookeeper_quorum：2181：/ hbase_znode    或

JDBC：凤：zookeeper_quorum：/ hbase_znode

（默认情况下，zookeeper侦听端口2181 。）

zookeeper_quorum - 可以是逗号分隔的服务器名称（必须是完全限定的DNS名称） hbase_znode - hbase或hbase-unsecured

e.g。

JDBC：凤：server1.abc.com，server2.abc.com：2181：/ HBase的

因为zookeeper无法连接到hbase
