Flink中常见的几种异常

问题一：
Exception in thread “main” org.apache.flink.table.api.TableException: Could not instantiate the executor. Make sure a planner module is on the classpath
at org.apache.flink.table.api.java.internal.StreamTableEnvironmentImpl.lookupExecutor(StreamTableEnvironmentImpl.java:147)
at org.apache.flink.table.api.java.internal.StreamTableEnvironmentImpl.create(StreamTableEnvironmentImpl.java:116)
at org.apache.flink.table.api.java.StreamTableEnvironment.create(StreamTableEnvironment.java:112)
at com.cn.flink.function.MyStreamingSource$StreamingDemo.main(MyStreamingSource.java:185)
Caused by: org.apache.flink.table.api.NoMatchingTableFactoryException: Could not find a suitable table factory for ‘org.apache.flink.table.delegation.ExecutorFactory’ in

Exception in thread "main" org.apache.flink.table.api.TableException: Could not instantiate the executor. Make sure a planner module is on the classpath

解决方案
缺少pom文件

        
            org.apache.flink
            flink-table-planner-blink_${scala.binary.version}
            ${flink.version}
        

在此运行解决

问题二
Field types of query result and registered TableSink do not match.
返回结果时使用对象时类型与返回结果不对应
解决方案
先查看表结构

Table queryTable = bsTableEnv.sqlQuery ("select a.id,a.name,b.id,b.name from evenTable as a join oddTable as b on a.name = b.name");
            queryTable.printSchema ();

在创建对应的样例类

返回即可

解决
问题三Too many fields referenced from an atomic type.

由于手敲前面忘了加public公共的
解决方案

已解决
