Hi Kevin, 这是什么版本？ Doc类能完整提供下吗？方便我们复现。
Best, Jingsong Lee ------------------------------------------------------------------ From:Kevin Liao <[email protected]> Send Time:2020年1月13日(星期一) 17:37 To:user-zh <[email protected]> Subject:blink planner的org.apache.flink.table.api.ValidationException报错 tEnv.connect(new Kafka() .version("universal") .topic("xxx") .startFromLatest() .property("bootstrap.servers", "xxxx") .property("group.id", "xxxx")) .withFormat(new Json().failOnMissingField(false).deriveSchema()) .withSchema(new Schema() // .field("logger_name", Types.STRING) // .field("host", Types.STRING) // .field("@timestamp", Types.SQL_TIMESTAMP) // .field("_rowtime", Types.SQL_TIMESTAMP) // .rowtime( // new Rowtime().timestampsFromField("@timestamp").watermarksPeriodicBounded(1000)) .field("doc", Types.POJO(Doc.class)) ) .inAppendMode() .registerTableSource("xxx"); Table result = tEnv.sqlQuery( "SELECT doc.xxx1, doc.xxx2, ... , doc.xxxN as seq FROM xxx"); // result.printSchema(); tEnv.toAppendStream(result, new TupleTypeInfo<>(STRING, STRING, STRING, STRING, STRING, STRING, STRING, STRING, STRING, STRING, BOOLEAN, LONG, STRING, STRING, STRING, STRING, STRING, STRING, STRING, LONG, STRING, INT, STRING, INT)).print(); 以上代码在 flink planner 下可以运行，但切换到 blink planner 则报错如下： 、、、 Exception in thread "main" org.apache.flink.table.api.ValidationException: Type LEGACY(PojoType<com.sogou.qidian.Doc, fields = [（。。。。// 省略）]>) of table field 'doc' does not match with type PojoType<com.sogou.qidian.Doc, fields = [(。。。。//省略)]> of the field 'doc' of the TableSource return type. at org.apache.flink.table.planner.sources.TableSourceUtil$$anonfun$4.apply(TableSourceUtil.scala:121) at org.apache.flink.table.planner.sources.TableSourceUtil$$anonfun$4.apply(TableSourceUtil.scala:92) at scala.collection.TraversableLike$$anonfun$map$1.apply(TraversableLike.scala:234) at scala.collection.TraversableLike$$anonfun$map$1.apply(TraversableLike.scala:234) at scala.collection.IndexedSeqOptimized$class.foreach(IndexedSeqOptimized.scala:33) at scala.collection.mutable.ArrayOps$ofRef.foreach(ArrayOps.scala:186) at scala.collection.TraversableLike$class.map(TraversableLike.scala:234) at scala.collection.mutable.ArrayOps$ofRef.map(ArrayOps.scala:186) at org.apache.flink.table.planner.sources.TableSourceUtil$.computeIndexMapping(TableSourceUtil.scala:92) at org.apache.flink.table.planner.plan.nodes.physical.stream.StreamExecTableSourceScan.translateToPlanInternal(StreamExecTableSourceScan.scala:100) at org.apache.flink.table.planner.plan.nodes.physical.stream.StreamExecTableSourceScan.translateToPlanInternal(StreamExecTableSourceScan.scala:55) at org.apache.flink.table.planner.plan.nodes.exec.ExecNode$class.translateToPlan(ExecNode.scala:54) at org.apache.flink.table.planner.plan.nodes.physical.stream.StreamExecTableSourceScan.translateToPlan(StreamExecTableSourceScan.scala:55) at org.apache.flink.table.planner.plan.nodes.physical.stream.StreamExecCalc.translateToPlanInternal(StreamExecCalc.scala:86) at org.apache.flink.table.planner.plan.nodes.physical.stream.StreamExecCalc.translateToPlanInternal(StreamExecCalc.scala:46) at org.apache.flink.table.planner.plan.nodes.exec.ExecNode$class.translateToPlan(ExecNode.scala:54) at org.apache.flink.table.planner.plan.nodes.physical.stream.StreamExecCalc.translateToPlan(StreamExecCalc.scala:46) at org.apache.flink.table.planner.plan.nodes.physical.stream.StreamExecSink.translateToTransformation(StreamExecSink.scala:185) at org.apache.flink.table.planner.plan.nodes.physical.stream.StreamExecSink.translateToPlanInternal(StreamExecSink.scala:154) at org.apache.flink.table.planner.plan.nodes.physical.stream.StreamExecSink.translateToPlanInternal(StreamExecSink.scala:50) at org.apache.flink.table.planner.plan.nodes.exec.ExecNode$class.translateToPlan(ExecNode.scala:54) at org.apache.flink.table.planner.plan.nodes.physical.stream.StreamExecSink.translateToPlan(StreamExecSink.scala:50) at org.apache.flink.table.planner.delegation.StreamPlanner$$anonfun$translateToPlan$1.apply(StreamPlanner.scala:61) at org.apache.flink.table.planner.delegation.StreamPlanner$$anonfun$translateToPlan$1.apply(StreamPlanner.scala:60) at scala.collection.TraversableLike$$anonfun$map$1.apply(TraversableLike.scala:234) at scala.collection.TraversableLike$$anonfun$map$1.apply(TraversableLike.scala:234) at scala.collection.Iterator$class.foreach(Iterator.scala:891) at scala.collection.AbstractIterator.foreach(Iterator.scala:1334) at scala.collection.IterableLike$class.foreach(IterableLike.scala:72) at scala.collection.AbstractIterable.foreach(Iterable.scala:54) at scala.collection.TraversableLike$class.map(TraversableLike.scala:234) at scala.collection.AbstractTraversable.map(Traversable.scala:104) at org.apache.flink.table.planner.delegation.StreamPlanner.translateToPlan(StreamPlanner.scala:60) at org.apache.flink.table.planner.delegation.PlannerBase.translate(PlannerBase.scala:149) at org.apache.flink.table.api.java.internal.StreamTableEnvironmentImpl.toDataStream(StreamTableEnvironmentImpl.java:319) at org.apache.flink.table.api.java.internal.StreamTableEnvironmentImpl.toAppendStream(StreamTableEnvironmentImpl.java:227) at com.sogou.qidian.BatchJob.main(BatchJob.java:83) Execution failed for task ':BatchJob.main()'. > Process 'command '/Users/liaoxu/.sdkman/candidates/java/current/bin/java'' > finished with non-zero exit value 1 、、、 仔细比对了报错日志里两个 Doc类型是相同的 谢谢
