HI,大家好:
我有一个应用场景,利用Flinksql读取Kafka数据写入Kudu,由于官方没有Kudu Connector,自定义了一个Kudu Sink Connector,在本地IDEA下测试可以 正常跑通; 可是将代码打包,并将kudu-client.jar的依赖包放置Flink的lib目录下之后,提交任务到集群报错如下: java.lang.NoClassDefFoundError: com/stumbleupon/async/Callback at org.apache.kudu.client.AsyncKuduClient$AsyncKuduClientBuilder.build(AsyncKuduClient.java:2525) ~[kudu-client-1.9.0.jar:1.9.0] at org.apache.kudu.client.KuduClient$KuduClientBuilder.build(KuduClient.java:533) ~[kudu-client-1.9.0.jar:1.9.0] at com.java.flink.sql.kudu.KuduSinkFunction.open(KuduSinkFunction.java:38) ~[FlinkProject.jar:?] at org.apache.flink.api.common.functions.util.FunctionUtils.openFunction(FunctionUtils.java:36) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator.open(AbstractUdfStreamOperator.java:102) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.table.runtime.operators.sink.SinkOperator.open(SinkOperator.java:63) ~[flink-table-blink_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.runtime.tasks.OperatorChain.initializeStateAndOpenOperators(OperatorChain.java:401) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.runtime.tasks.StreamTask.lambda$beforeInvoke$2(StreamTask.java:507) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.runtime.tasks.StreamTaskActionExecutor$SynchronizedStreamTaskActionExecutor.runThrowing(StreamTaskActionExecutor.java:92) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.runtime.tasks.StreamTask.beforeInvoke(StreamTask.java:501) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:531) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.runtime.taskmanager.Task.doRun(Task.java:722) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.runtime.taskmanager.Task.run(Task.java:547) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at java.lang.Thread.run(Thread.java:748) ~[?:1.8.0_162] Suppressed: java.lang.NullPointerException at com.java.flink.sql.kudu.KuduSinkFunction.close(KuduSinkFunction.java:86) ~[FlinkProject.jar:?] at org.apache.flink.api.common.functions.util.FunctionUtils.closeFunction(FunctionUtils.java:43) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator.dispose(AbstractUdfStreamOperator.java:117) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.runtime.tasks.StreamTask.disposeAllOperators(StreamTask.java:740) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.runtime.tasks.StreamTask.runAndSuppressThrowable(StreamTask.java:720) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.runtime.tasks.StreamTask.cleanUpInvoke(StreamTask.java:643) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:552) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.runtime.taskmanager.Task.doRun(Task.java:722) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at org.apache.flink.runtime.taskmanager.Task.run(Task.java:547) ~[flink-dist_2.11-1.12.0.jar:1.12.0] at java.lang.Thread.run(Thread.java:748) ~[?:1.8.0_162] Caused by: java.lang.ClassNotFoundException: com.stumbleupon.async.Callback at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[?:1.8.0_162] at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[?:1.8.0_162] at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:338) ~[?:1.8.0_162] at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[?:1.8.0_162] ... 14 more 不是很清楚这个 com.stumbleupon.async.Callback 类的依赖来自哪里,该怎么解决? | | superainbower | | [hidden email] | 签名由网易邮箱大师定制 |

hi,
1.在kudu-client.jar里,按你的方式grep不到,本地idea下启动只引入了 这一个依赖,是可以运行,所以将这个kudu-client的依赖直接放到了lib下,难道还要引入其他依赖吗? 2.你说的对,close是可判空一下 在2020年12月30日 18:33,hailongwang 写道: 这个应该是 `kudu-client.jar` 里面应该打进去的吧。 可以看下 jar -tf kudu-client.jar | grep 'com.stumbleupon.async.Callback' ps: 你的 close 方法有 npe,应该是 客户端还没构建出来,可以判空下。 Best, Hailong 在 2020-12-30 17:24:48,"superainbower" <[hidden email]> 写道: >HI,大家好: >我有一个应用场景,利用Flinksql读取Kafka数据写入Kudu,由于官方没有Kudu Connector,自定义了一个Kudu Sink Connector,在本地IDEA下测试可以 正常跑通; >可是将代码打包,并将kudu-client.jar的依赖包放置Flink的lib目录下之后,提交任务到集群报错如下: > > >java.lang.NoClassDefFoundError: com/stumbleupon/async/Callback > at org.apache.kudu.client.AsyncKuduClient$AsyncKuduClientBuilder.build(AsyncKuduClient.java:2525) ~[kudu-client-1.9.0.jar:1.9.0] > at org.apache.kudu.client.KuduClient$KuduClientBuilder.build(KuduClient.java:533) ~[kudu-client-1.9.0.jar:1.9.0] > at com.java.flink.sql.kudu.KuduSinkFunction.open(KuduSinkFunction.java:38) ~[FlinkProject.jar:?] > at org.apache.flink.api.common.functions.util.FunctionUtils.openFunction(FunctionUtils.java:36) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator.open(AbstractUdfStreamOperator.java:102) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.table.runtime.operators.sink.SinkOperator.open(SinkOperator.java:63) ~[flink-table-blink_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.runtime.tasks.OperatorChain.initializeStateAndOpenOperators(OperatorChain.java:401) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.runtime.tasks.StreamTask.lambda$beforeInvoke$2(StreamTask.java:507) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.runtime.tasks.StreamTaskActionExecutor$SynchronizedStreamTaskActionExecutor.runThrowing(StreamTaskActionExecutor.java:92) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.runtime.tasks.StreamTask.beforeInvoke(StreamTask.java:501) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:531) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.runtime.taskmanager.Task.doRun(Task.java:722) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.runtime.taskmanager.Task.run(Task.java:547) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at java.lang.Thread.run(Thread.java:748) ~[?:1.8.0_162] > Suppressed: java.lang.NullPointerException > at com.java.flink.sql.kudu.KuduSinkFunction.close(KuduSinkFunction.java:86) ~[FlinkProject.jar:?] > at org.apache.flink.api.common.functions.util.FunctionUtils.closeFunction(FunctionUtils.java:43) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator.dispose(AbstractUdfStreamOperator.java:117) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.runtime.tasks.StreamTask.disposeAllOperators(StreamTask.java:740) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.runtime.tasks.StreamTask.runAndSuppressThrowable(StreamTask.java:720) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.runtime.tasks.StreamTask.cleanUpInvoke(StreamTask.java:643) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:552) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.runtime.taskmanager.Task.doRun(Task.java:722) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at org.apache.flink.runtime.taskmanager.Task.run(Task.java:547) ~[flink-dist_2.11-1.12.0.jar:1.12.0] > at java.lang.Thread.run(Thread.java:748) ~[?:1.8.0_162] >Caused by: java.lang.ClassNotFoundException: com.stumbleupon.async.Callback > at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[?:1.8.0_162] > at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[?:1.8.0_162] > at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:338) ~[?:1.8.0_162] > at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[?:1.8.0_162] > ... 14 more > > >不是很清楚这个 com.stumbleupon.async.Callback 类的依赖来自哪里,该怎么解决? >| | >superainbower >| >| >[hidden email] >| >签名由网易邮箱大师定制 > |
补充一下,在git上Cloudera/kudu 下的 org.apache.kudu.client.AsyncKuduClient这个类里面,确实看到 import com.stumbleupon.async.Callback
