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 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？

flink per job不能够在同一jar包中执行两次main方法吗？
