大家好：
我的flink是部署在yarn上左session，今天早上jobmanager自动退出了，然后yarn把他重新拉起了，导致里面跑的job重新启动了，但是我查看日志，看到jobmanager的日志没有任何异常，同时jobmanager也没有长时间的full gc和频繁的gc，以下是jobmanager的日志： 就是在06:44分的是偶，日志上标记了收收到停止请求，然后jobmanager直接停止了...请问是由于什么原因导致的呢？ 2019-08-06 06:43:58,891 INFO > org.apache.flink.runtime.checkpoint.CheckpointCoordinator -
