Hi, 如果org.apache.flink.table.factories.TableFactory里面没有KafkaTableSourceSinkFactory，那就是打包有问题。不清楚1.9的是怎么运行起来的，但是所有的jar的meta-inf-services文件都没有KafkaTableSourceSinkFactory，那也不应该能运行起来的。
推荐打包方式用shade，shade会merge meta-inf-services的文件的。 Best, Jingsong Lee On Wed, Apr 22, 2020 at 7:31 PM 宇张 <zhan...@akulaku.com> wrote: > > 》也确认下org.apache.flink.table.factories.TableFactory的内容，里面有没有KafkaTableSourceSinkFactory > > 这个我看了一下我先前flink1.9的工程，应用程序Jar里面也是没有这个类的，但是程序运行加载是没问题的，这么对比貌似就不是maven打包的问题了。。。。。 > > On Wed, Apr 22, 2020 at 7:22 PM 宇张 <zhan...@akulaku.com> wrote: > > > > > > 》也确认下org.apache.flink.table.factories.TableFactory的内容，里面有没有KafkaTableSourceSinkFactory > > 这个没有，只有org.apache.flink.formats.json.JsonRowFormatFactory > > 》拿到ClassLoader后看下能不能取到KafkaTableSourceSinkFactory的class > > 这个能拿到 > > > > 这么看来 貌似是 mvn打包有问题： > > mvn clean package -DskipTests > > 依赖范围为默认 > > > > > > On Wed, Apr 22, 2020 at 7:05 PM Jingsong Li <jingsongl...@gmail.com> > > wrote: > > > >> Hi, > >> > >> > >> > 也确认下org.apache.flink.table.factories.TableFactory的内容，里面有没有KafkaTableSourceSinkFactory > >> > >> > 这个指的是打印当前线程的classloader嘛Thread.currentThread().getContextClassLoader() > >> 是的，拿到ClassLoader后看下能不能取到KafkaTableSourceSinkFactory的class > >> > >> Best, > >> Jingsong Lee > >> > >> On Wed, Apr 22, 2020 at 7:00 PM 宇张 <zhan...@akulaku.com> wrote: > >> > >> > 看下你打包的 UberJar 里有没一个内容包括 > >> > 1、下面这个文件是存在的 > >> > > org.apache.flink.streaming.connectors.kafka.KafkaTableSourceSinkFactory > >> > 的文件 > >> > META-INF/services/org.apache.flink.table.factories.TableFactory > >> > 2、flink版本1.10，Standalone模式启动服务（start-cluster.sh），flink > >> > run运行(/software/flink-1.10.0/bin/flink run -c com.data.main.StreamMain > >> > ./flink_1.10_test-1.0-jar-with-dependencies.jar) > >> > 3、再确认下"TableEnvironmentImpl.sqlQuery"调用时候的ThreadClassLoader？ > >> > 这个指的是打印当前线程的classloader嘛Thread.currentThread().getContextClassLoader() > >> > > >> > > >> > > >> > On Wed, Apr 22, 2020 at 6:00 PM Jingsong Li <jingsongl...@gmail.com> > >> > wrote: > >> > > >> > > Hi, > >> > > > >> > > 先确认下你的Jar包里有没有 meta-inf-services的文件？里面确定有Kafka？ > >> > > > >> > > 如果有，再确认下"TableEnvironmentImpl.sqlQuery"调用时候的ThreadClassLoader? > >> > > 因为现在默认是通过ThreadClassLoader来获取Factory的。 > >> > > > >> > > Best, > >> > > Jingsong Lee > >> > > > >> > > On Wed, Apr 22, 2020 at 5:30 PM 宇张 <zhan...@akulaku.com> wrote: > >> > > > >> > > > 我这面使用Standalone模式运行Flink任务，但是Uber > >> > > > Jar里面的TableSourceFactory不能被加载，即使设置了classloader.resolve-order: > >> > > > child-first，只有放在lib目录才能加载得到，我看发布文档跟改了类加载策略，但是我不知道为什么Uber > >> > > Jar里面的Factory不能被加载 > >> > > > Flink Client respects Classloading Policy (FLINK-13749 > >> > > > <https://issues.apache.org/jira/browse/FLINK-13749>) > >> > > > < > >> > > > > >> > > > >> > > >> > https://ci.apache.org/projects/flink/flink-docs-release-1.10/release-notes/flink-1.10.html#flink-client-respects-classloading-policy-flink-13749 > >> > > > > > >> > > > > >> > > > The Flink client now also respects the configured classloading > >> policy, > >> > > > i.e., parent-first or child-first classloading.
