Application application_1512618719369_147804 failed 2 times due to ApplicationMaster for attempt app

本文记录了一次Hive任务持续报错的排查过程,通过分析发现nodemanager进程CPU占用过高导致任务失败,重启nodemanager后问题解决。

今天遇到一个特别怪的问题,之前etl中的hive任务一直报错,持续一上午,也没有查出原因,错误的任务的日志也找到,原本可以找到原因,但是打开日志,心里面一凉,什么报错也没有,不知所错。最后观察报错的节点,最终集中到两台机器,那就看看是不是这两台机器的hadoop的程序引起的吗?看看他们的程序都在,但是查看nodemanager的日志一直报错,并且查看cpu,nodemanager进程占用的cpu达1000%多,马上眼前一亮,知道cpu占用太多,导致ap不能联系,导致任务失败,最后把这两台机器的nodemanager重启一下,观察了一下,任务不在报错。继续努力.............
