一、今天在使用Hive对数据处理时，遇到了这个问题！
执行命令：
hive> select distinct etl(name,region,huxing,area,chaoxiang,zhuangxiu,dianti,danPrice,sumPrice) from house where sumprice>=300;
执行结束后报如下错误：
Application application_1543456255999_0001 failed 2 times due to Error launching appattempt_1543456255999_0001_000002. Got exception: org.apache.hadoop.yarn.exceptions.YarnException: Unauthorized request to start container.

二、问题处理方案
通过查看日志，以为是 yarn 配置文件有问题，经过查看，并没有问题！最终死马当作活马医，经过查看虚拟内存，发现比较吃紧。试想给大点内存会不会好？
把虚拟机关闭后，将内存调大一倍。再次开启虚拟机，开启集群；进行hive的操作。最终命令执行成功！往往一些坑都是在最不起眼的地方，多去留意容易忽视的地方，就能找到解决方案！
