1、所有的日志中没有地方显示代码冲突,表层现象为Could not resolve ResourceManager address akka.tcp://flink@xxxxxxxxx.cn:38121/user/rpc/resourcemanager_*, retrying in 10000 ms: Could not connect to rpc endpoint under address akka.tcp://xxxxxxx.cn:38121/user/rpc/resourcemanager_*. 很难联想到jar包...
类似于“Could not resolve ResourceManager address akka.tcp”这样的错误提示表明TaskManager无法连接到ResourceManager。检查ResourceManager的地址和端口是否正确配置,并且ResourceManager本身是否启动并处于可用状态。 如果确实怀疑是Akka通信问题,可以进一步查看Flink的Akka配置部分,以及Akka的日志级别设定,以便抓取更多的调试信息来...

当我在kubernetes(v1.15.2)集群中启动apacheflink1.10任务管理器服务时,它显示如下日志: 2020-05-01 08:34:55,847 INFO org.apache.flink.runtime.taskexecutor.TaskExecutor- Could not resolve ResourceManager address akka.tcp://flink@flink- 浏览277提问于2020-05-01得票数 0 ...
首先我们先来大概聊一下这个服务的功能,从变量名称可以猜出,这个服务是为了获取ResourceManager的地址,同时添加针对于ResourceManager的监听,在获取到ResourceManager的地址之后,就会开始对当前的TaskExecutor进行注册了。如果注册失败,则报错并直接关闭JVM,如果注册成功,则开始维持和ResourceManager的心跳,并向ResourceManager做自身...
