flink作业报 task manager连接错误

星夜
flink作业在执行几个小时候总是报某一个节点失去连接的错误,有没有朋友遇到过?




报错日志如下:

org.apache.flink.runtime.io.network.netty.exception.RemoteTransportException: Connection unexpectedly closed by remote task manager 'cdh-slave-01/130.0.0.1:41800'. This might indicate that the remote task manager was lost.

你好,
可以看下具体那个 TaskManager 的日志,我之前遇到的这种情况一般都是内存用超被容器(比如Yarn)Kill 掉或者是 TaskManager
里面抛异常了。如果是 received signal 15 一般就是被容器 kill 掉了,可以看下容器的日志,其他情况可以看下具体的异常。
