我正在使用Direct Runner使用Netezza JDBC驱动程序从Netezza读取数据。我收到以下异常-org.apache.beam.sdk.util.UserCodeException：java.lang.AbstractMethodError：org.netezza.sql.NzConnection.isValid（I）Z。可能是什么分辨率？
下面的示例代码：
PCollection<KV<String, String>> a = pipeline.apply(JdbcIO.<KV<String, String>>read()
.withCoder(KvCoder.of(StringUtf8Coder.of(), StringUtf8Coder.of()))
.withDataSourceConfiguration(JdbcIO.DataSourceConfiguration.create(
"org.netezza.Driver", "jdbc:netezza://<server name>:<port>/<databasename>")
.withUsername("<username>")
.withPassword("<password>"))
.withQuery("select column1,column2 from tmp_table")
.withRowMapper(new JdbcIO.RowMapper<KV<String, String>>() {
@Override
public KV<String, String> mapRow(ResultSet resultSet) throws Exception {
System.out.println("Rows" + resultSet.getString(1) + resultSet.getString(2));
return KV.of(resultSet.getString(1), resultSet.getString(2));
}
})
);
例外：
