Flink作业性能

您可以查看运行中作业的性能，包括Job Manager与运行Task Managers的CPU、内存和线程的使用情况，这可以协助您定位代码问题，例如作业代码是否存在问题、个别类是否初始化比较慢、个别类是否占用资源比较多等问题。本文为您介绍如何查看作业Job Manager和运行Task Managers的性能。

Flink自动重启的task和手动启动job有啥差异么？有手段能让自动重启也达到手动重启的效果么？

任务运行一段时间后，任务出现异常触发task自动重启，然后一直报连接超时问题，org.apache.flink.shaded.netty4.io.netty.channel.ConnectTimeoutException: connection timed out: /10.0.0.16:42193，通过手动cancel job 再重新submit 后，就没有连接超时异常了。Flink自动重启的....

flink restart策略自动重启job时会不会再执行一遍用户jar包里面的main函数？

有没有哪些同学知道flink restart策略自动重启job时会不会再执行一遍用户jar包里面的main函数？就是我以yarn-per-job模式提交了一个jar包执行flink任务，然后main函数肯定是在本地节点运行后再将整个job提交到yarn生成flink集群的，但是要是我这个flink任务挂了触发自动重启的话，还会再进行一遍这个提交过程吗？
