flink table 查询报 unexpected block data

[ChewJ404]

前置信息

• 用的 apache/flink:1.14.5-scala_2.11-java8 镜像
• flink-sql-connector-mysql-cdc-2.2.1.jar cdc 包
• job与 task 节点都配置了 conf/flink-conf.yaml 已经 配置了 classloader.resolve-order: parent-first

结果

求教 如何 查证 是 啥原因

lib 目录下 jar

flink-csv-1.14.5.jar
flink-dist_2.11-1.14.5.jar
flink-json-1.14.5.jar
flink-shaded-zookeeper-3.4.14.jar
flink-sql-connector-mysql-cdc-2.2.1.jar
flink-table_2.11-1.14.5.jar
log4j-1.2-api-2.17.1.jar
log4j-api-2.17.1.jar
log4j-core-2.17.1.jar
log4j-slf4j-impl-2.17.1.jar

查了下原因 错误意思是：ObjectInputStream，流转对象 反序列化。不匹 配报错

[ChewJ404]

解决了 ，傻了 原来是 task 节点 lib 下 没加 cdc jar

牛逼兄弟 我也是这样解决了
