一、今天在使用Hive對資料處理時，遇到了這個問題！
執行命令：
hive> select distinct etl(name,region,huxing,area,chaoxiang,zhuangxiu,dianti,danPrice,sumPrice) from house where sumprice>=300;
執行結束後報如下錯誤：

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、問題處理方案
通過檢視日誌，以為是 yarn 配置檔案有問題，經過檢視，並沒有問題！最終死馬當作活馬醫，經過檢視虛擬記憶體，發現比較吃緊。試想給大點記憶體會不會好？
把虛擬機器關閉後，將記憶體調大一倍。再次開啟虛擬機器，開啟叢集；進行hive的操作。最終命令執行成功！往往一些坑都是在最不起眼的地方，多去留意容易忽視的地方，就能找到解決方案！
