1. flink1.11解压后，启动会报： java.lang.NoClassDefFoundError: com/sun/jersey/core/util/FeaturesAndProperties 然后将jersey-client-1.9.jar、jersey-core-1.9.jar复制到lib下 2. 再次启动，报错： Caused by: java.lang.ClassNotFoundException: javax.ws.rs.ext.MessageBodyReader 然后将javax.ws.rs-api-2.1.1.jar复制到lib下 3. 再次启动，报错： Caused by: java.lang.ClassNotFoundException: org.glassfish.jersey.internal.RuntimeDelegateImpl 将jersey-common-3.0.0-M6.jar复制到lib下 4. 再次启动，报错： Caused by: java.lang.ClassNotFoundException: jakarta.ws.rs.ext.RuntimeDelegate 将jakarta.ws.rs-api-3.0.0-M1.jar复制到lib下 5. 再次启动，报： java.lang.LinkageError: ClassCastException: attempting to castjar:file:/data/server/flink-1.11.0/lib/javax.ws.rs-api-2.1.1.jar!/javax/ws/rs/ext/RuntimeDelegate.class to jar:file:/data/server/flink-1.11.0/lib/javax.ws.rs-api-2.1.1.jar!/javax/ws/rs/ext/RuntimeDelegate.class 6. 我崩溃了
在2020年07月20日 20:06，Leonard Xu<[email protected]> 写道： Hi, 看起来像是依赖冲突问题，报错信息看起来是classpath加载到了两个相同的jar, javax.ws.rs-api-2.1.1.jar 这个jar包是你集群需要的吗？ 可以把你场景说细点，比如这个问题如何复现，这样大家可以帮忙一起排查 祝好， Leonard Xu 在 2020年7月20日，15:36，酷酷的浑蛋 <[email protected]> 写道： Flink1.11启动时报错： java.lang.LinkageError: ClassCastException: attempting to castjar:file:/data/rt/jar_version/sql/6.jar!/javax/ws/rs/ext/RuntimeDelegate.class to jar:file:/data/server/flink-1.11.0/lib/javax.ws.rs-api-2.1.1.jar!/javax/ws/rs/ext/RuntimeDelegate.class at javax.ws.rs.ext.RuntimeDelegate.findDelegate(RuntimeDelegate.java:125) at javax.ws.rs.ext.RuntimeDelegate.getInstance(RuntimeDelegate.java:97) at javax.ws.rs.core.MediaType.valueOf(MediaType.java:172) at com.sun.jersey.core.header.MediaTypes.<clinit>(MediaTypes.java:65) at com.sun.jersey.core.spi.factory.MessageBodyFactory.initReaders(MessageBodyFactory.java:182) at com.sun.jersey.core.spi.factory.MessageBodyFactory.initReaders(MessageBodyFactory.java:175) at com.sun.jersey.core.spi.factory.MessageBodyFactory.init(MessageBodyFactory.java:162) at com.sun.jersey.api.client.Client.init(Client.java:342) at com.sun.jersey.api.client.Client.access$000(Client.java:118) at com.sun.jersey.api.client.Client$1.f(Client.java:191) at com.sun.jersey.api.client.Client$1.f(Client.java:187) at com.sun.jersey.spi.inject.Errors.processWithErrors(Errors.java:193) at com.sun.jersey.api.client.Client.<init>(Client.java:187) at com.sun.jersey.api.client.Client.<init>(Client.java:170) at org.apache.hadoop.yarn.client.api.impl.TimelineClientImpl.serviceInit(TimelineClientImpl.java:280) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) at org.apache.hadoop.yarn.client.api.impl.YarnClientImpl.serviceInit(YarnClientImpl.java:169) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) at org.apache.flink.yarn.YarnClusterClientFactory.getClusterDescriptor(YarnClusterClientFactory.java:76) at org.apache.flink.yarn.YarnClusterClientFactory.createClusterDescriptor(YarnClusterClientFactory.java:61) at org.apache.flink.yarn.YarnClusterClientFactory.createClusterDescriptor(YarnClusterClientFactory.java:43) at org.apache.flink.client.deployment.executors.AbstractJobClusterExecutor.execute(AbstractJobClusterExecutor.java:64) at org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.executeAsync(StreamExecutionEnvironment.java:1812) at org.apache.flink.client.program.StreamContextEnvironment.executeAsync(StreamContextEnvironment.java:128) at org.apache.flink.client.program.StreamContextEnvironment.execute(StreamContextEnvironment.java:76) at org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.execute(StreamExecutionEnvironment.java:1699) at com.missfresh.Main.main(Main.java:142) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.flink.client.program.PackagedProgram.callMainMethod(PackagedProgram.java:288) at org.apache.flink.client.program.PackagedProgram.invokeInteractiveModeForExecution(PackagedProgram.java:198) at org.apache.flink.client.ClientUtils.executeProgram(ClientUtils.java:149) at org.apache.flink.client.cli.CliFrontend.executeProgram(CliFrontend.java:699) at org.apache.flink.client.cli.CliFrontend.run(CliFrontend.java:232) at org.apache.flink.client.cli.CliFrontend.parseParameters(CliFrontend.java:916) at org.apache.flink.client.cli.CliFrontend.lambda$main$10(CliFrontend.java:992) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1754) at org.apache.flink.runtime.security.contexts.HadoopSecurityContext.runSecured(HadoopSecurityContext.java:41) at org.apache.flink.client.cli.CliFrontend.main(CliFrontend.java:992) 我已经在lib下添加了javax.ws.rs-api-2.1.1.jar
