Project: Flink
Issue Type: Bug
Components: DataStream API, Scala API
Affects Versions: 1.3.2
Environment: Flink 1.3.2 , Yarn Cluster, FsStateBackend
Reporter: Shashank Agarwal
I am using many CEP's and Global Window. I am getting following error sometimes and application crashes. I have checked logically there's no flow in the program. Here ItemPojo is a Pojo class and we are using java.utill.List[ItemPojo]. We are using Scala DataStream API please find attached logs.
