Flink CDC 里java.lang.IllegalStateException: Failed to send request to coordinator: com.ververica.cdc.runtime.operators.schema.event.SchemaChangeRequest@3d93dee1 mysql->Doris的整库同步,没有成功自动建表以及同步数据?Flink 1.16.2 cdc3.0。Caused by: java.util.concurrent.ExecutionException: java.util.concurrent.TimeoutException: Invocation of [RemoteRpcInvocation(JobMasterOperatorEventGateway.sendRequestToCoordinator(OperatorID, SerializedValue))] at recipient [akka.tcp://flink@10.7.70.137:6123/user/rpc/jobmanager_2] timed out. This is usually caused by: 1) Akka failed sending the message silently, due to problems like oversized payload or serialization failures. In that case, you should find detailed error information in the logs. 2) The recipient needs more time for responding, due to problems like slow machines or network jitters. In that case, you can try to increase akka.ask.timeout.测试Flink cdc3.0的整库同步功能,mysql to doris Pipeline同步,Flink1.17.1 、cdc3.0.0、mysql8.0.26、doris2.0.2.1。看日志成功读取到了mysql数据库库表信息,没做变更mysql的schema信息,而且我cdc的yaml文件里面也添加了参数 table.create.properties.light_schema_change: true。
用flink1.17.0把akka.ask.timeout这个参数调至120s 试一下 。你到jobmanager的config中搜索 一下akka.ask.timeout这个参数。link session 需要重启一下这个配置才能生效。另外这个问题已经在修复了。此回答来自钉群Flink CDC 社区。
