Paimon Flink本地读取数据报错

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

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：

<dependency><groupId>org.apache.paimon</groupId><artifactId>paimon-flink-1.18</artifactId><version>0.8.0</version></dependency><dependency><groupId>org.apache.hadoop</groupId><artifactId>hadoop-client</artifactId><version>3.3.6</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.28</version></dependency><dependency><groupId>org.apache.flink</groupId><artifactId>flink-core</artifactId><version>1.18.0</version></dependency><!-- https://mvnrepository.com/artifact/org.apache.flink/flink-table-planner --><dependency><groupId>org.apache.flink</groupId><artifactId>flink-table-planner_2.12</artifactId><version>1.18.0</version></dependency><!-- https://mvnrepository.com/artifact/org.apache.flink/flink-table-api-java --><dependency><groupId>org.apache.flink</groupId><artifactId>flink-table-api-java</artifactId><version>1.18.0</version></dependency><dependency><groupId>org.apache.flink</groupId><artifactId>flink-clients</artifactId><version>1.18.0</version></dependency>

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>

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

从上面大概可以看出应该是缺flink-connector-files依赖，添加上去之后成功了

<dependency><groupId>org.apache.flink</groupId><artifactId>flink-connector-files</artifactId><version>1.18-SNAPSHOT</version>
</dependency>
