1.idea本地读取paimon
用idea在本地读取paimon的表时需要添加的依赖除了官网提出的和hadoop相关的，paimon-flink之类相关的除外还需要其他额外依赖
java
import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment;
import org.apache.flink.table.api.bridge.java.StreamTableEnvironment;
public class Test {
public static void main(String[] args) {
StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env);
tableEnv.executeSql(
"CREATE CATALOG my_jdbc WITH (\n" +
"'type' = 'paimon',\n" +
"'metastore' = 'jdbc',\n" +
"'uri' = 'jdbc:mysql://test3:3306/paimon',\n" +
"'jdbc.user' = 'root',\n" +
"'jdbc.password' = 'N^57F9m2RI#rp8',\n" +
"'catalog-key'='jdbc',\n" +
"'warehouse' = 'hdfs://test1:8020/user/paimon'\n" +
" )");
tableEnv.executeSql("use catalog my_jdbc");
tableEnv.sqlQuery("select * from test").execute().print();
}
}以上是我的代码，用的jdbc catalog读取hadoop上的数据，下面是最开始的依赖：

... 25 more从报错大概可以看出需要这个 org/apache/flink/connector/base路径底下的source/hybrid/HybridSource$SourceFactory类，查了一下这个类在flink-connector-base类里面，所以添加上这个依赖：
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-connector-base</artifactId>
<version>1.18.0</version>
</dependency>3.报错2
加上了上面的依赖继续跑然后又报错了：NoClassDefFoundError: org/apache/flink/connector/file/src/reader/BulkFormat$RecordIterator
