在Apache的Storm JdbcInsertBolt
初始化期间,出现错误
java.lang.ClassCastException:
Cannot cast org.apache.phoenix.jdbc.PhoenixDriver to javax.sql.DataSource

来自基础HikariCPConnectionProvider
。怎么了?
我正在关注http://storm.apache.org/releases/1.1.2/storm-jdbc.html,基于此,我正在做的事情:
我喜欢通过Phoenix将数据从Apache Storm拓扑写入HBase表。为此,我从群集服务器下载了驱动程序文件(phoenix-4.7.0.2.6.5.3003-25-client.jar
),并将其添加到本地maven存储库中:
mvn install:install-file
-Dfile=lib\phoenix-4.7.0.2.6.5.3003-25-client.jar
-DgroupId=org.apache.phoenix
-DartifactId=phoenix-jdbc -Dversion=4.7.0 -Dpackaging=jar
此后,我更新了.pom
:
<dependency>
<groupId>org.apache.phoenix</groupId>
<artifactId>phoenix-jdbc</artifactId>
<version>4.7.0</version>
</dependency>
现在添加Storm的JDBC-Bolt:
<dependency>
<groupId>org.apache.storm</groupId>
<artifactId>storm-jdbc</artifactId>
<version>1.2.2</version>
<scope>provided</scope>
</dependency>
然后我准备使用螺栓。首先:设置连接提供程序:
Map hikariConfigMap = new HashMap();
hikariConfigMap.put("dataSourceClassName", "org.apache.phoenix.jdbc.PhoenixDriver");
hikariConfigMap.put("dataSource.url", "<zookeeperQuorumURI>:2181:/hbase-unsecure");
this.connectionProvider = new HikariCPConnectionProvider(hikariConfigMap);
现在将元组值初始化为db-columns-mapper
this.simpleJdbcMapper = new SimpleJdbcMapper(this.tablename, connectionProvider);
在此期间,发生上述错误。
仅出于完整性考虑:JdbcInsertBolt
的创建方式如下:
new JdbcInsertBolt(this.connectionProvider, this.simpleJdbcMapper)
.withTableName(this.tablename)
.withQueryTimeoutSecs(30);
答案 0 :(得分:1)
您是否尝试设置:
driverClassName -> org.apache.phoenix.jdbc.PhoenixDriver。当前代码似乎已经设置了dataSourceClassName,我猜这是不同的
