flink on yarn中,yarn的applicationMaster和flink
JobManager的关系是啥,我对yarn不是很熟悉,之前的理解是
JobManager就是yarn中的applicationMaster的角色。但我在官网中看到如下摘录:...Once that has
finished, the ApplicationMaster (AM) is started.The JobManager and AM are
running in the same container. Once they successfully started, the AM knows
the address of the JobManager (its own host). 说明 AM和JM是两个进程,可是我将flink
job提交到yarn集群,只看到有jobManager进程(YarnJobClusterEntrypoint),并没有看到过ApplicationMaster进程,请帮忙解释他们之间的联系和区别?
