我正在尝试通过hbase连接phoenix:
首先,我将phoenix-2.jar
添加到hbase lib目录中。
然后重新启动区域服务器,然后在netbeans中创建一个项目,并将phoenic-2-client.jar
添加到项目的类路径中。
然后将以下行添加到hbase.site.xml
中,用于hbase和phoenix。
<property>
<name>hbase.master</name>
<value>23.201.00.100:60000</value>
<description>The host and port the HBase master runs at.
</description>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2222</value>
<description>Property from ZooKeeper's config zoo.cfg.
The port at which the clients will connect.
</description>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>rs1.example.com,rs2.example.com,rs3.example.com,rs4.example.com,rs5.example.com</value>
<description>Comma separated list of servers in the ZooKeeper Quorum.
For example, "host1.mydomain.com,host2.mydomain.com,host3.mydomain.com".
By default this is set to localhost for local and pseudo-distributed modes
of operation. For a fully-distributed setup, this should be set to a full
list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is set in hbase-env.sh
this is the list of servers which we will start/stop ZooKeeper on.
</description>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/usr/local/zookeeper</value>
<description>Property from ZooKeeper's config zoo.cfg.
The directory where the snapshot is stored.
</description>
</property>
我的hbase是pseodo分配模式。最后,我在netbeans中编写了以下代码以连接到hbase:
Connection conn;
Properties prop = new Properties();
try{
Class.forName("com.salesforce.phoenix.jdbc.PhoenixDriver");
conn = DriverManager.getConnection("jdbc:phoenix:rs1.example.com,rs2.example.com,rs3.example.com,rs4.example.com,rs5.example.com:2222:hdfs://localhost:8020/hbase");
System.out.println(conn);
但显示此错误:
java.sql.SQLException: ERROR 102 (08001): Malformed connection url. jdbc:phoenix:rs1.example.com,rs2.example.com,rs3.example.com,rs4.example.com,rs5.example.com:2222:hdfs://localhost:8020/hbase

检查此link是否有帮助。
如Phoenix项目中所述,jdbc连接网址应如下所示:jdbc:phoenix:zookeeper1:port,zookeeper2:port
默认情况下,zookeeper侦听端口2181。
由于

正如错误清楚地说明的那样,您的数据库连接URL在getConnection
方法中出错:
jdbc:phoenix:rs1.example.com,rs2.example.com,rs3.example.com,rs4.example.com,rs5.example.com:2222:hdfs://localhost:8020/hbase
我相信你的jdbc连接网址应该是这样的:
jdbc:hbql;maxtablerefs=10;hbase.master=23.201.00.100:60000
答案 2 :(得分:0)
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:phoenix:zookeeper_quorum:2181:/ hbase_znode 或
<强> JDBC:凤:zookeeper_quorum:/ hbase_znode 强>
(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
答案 3 :(得分:0)
我使用的是Phoenix-4.7.0-HBase-1.1。如果您在伪分布式模式下运行,则可以立即执行connection = DriverManager.getConnection("jdbc:phoenix");
。只需确保您的Java程序可以与Master,Zookeeper和RegionServer通信。检查正在使用的端口和IP /主机名。在我的情况下(SSH隧道),我确保端口HMaster:16000,HQuorumPeer:2181和HRegionServer:16201没有被阻止。
