概述
在集群中启动Flink任务,任务启动成功,但使用socket发送数据的时候任务执行失败
后台使用flink run后执行任务的报错情况:

yarn界面已经显示该任务执行失败:
解决问题:代码中有关flink的scala版本是2.11的,而部署在集群的flink对应的scala版本是2.12的,所以是版本不一致导致的,两边对应的scala版本一致可解决该问题。
最后
以上就是乐观帽子为你收集整理的Flink任务执行失败:java.lang.NoSuchMethodError: scala.Predef$.refArrayOps([Ljava/lang/Object;)Lscala/collec的全部内容,希望文章能够帮你解决Flink任务执行失败:java.lang.NoSuchMethodError: scala.Predef$.refArrayOps([Ljava/lang/Object;)Lscala/collec所遇到的程序开发问题。
