实时计算 Flink版挂掉的相关内容

如果我flink程序挂掉了，我从checkpoint重启的话，会从source那里重新计算，还是从中

如果我flink程序挂掉了，我从checkpoint重启的话，会从source那里重新计算，还是从中间某个算子开始计算？

cancel掉flink的任务会导致taskManager节点挂掉。

flink部署的是stand alone，在flink web UI上提交的任务(job 并行度2)，进行cancel后会导致taskManager节点挂掉一个。在服务器上命令行用flink cancel jobID也是一样，会导致节点挂掉。

经常遇到 major GC 花了半分钟才完成，但一两秒以后又启动了，如此往复。这种情况下 Flink 很不稳定，随时可能挂掉，checkpoint 也完不成了，Flink 还在默默地往身上扛数据
