执行Hive查询：

Console是这样报错的

如果把同样的sql放到hive shell里面执行

FAILED
java.io.IOException: Rename cannot overwrite non empty destination directory /mnt/glusterfs/HadoopVol/hadoop/yarn/local/filecache/13

报错是上面这样的

一般出现这种情况，你去filecache 下面去找这个目录，是找不到的

原因可能是硬盘或者网络等原因 导致这个目录没有写入进去，删除filecache下面的所有文件夹，重启yarn 即可

重启之后你就会发现 filecache这个目录会重新创建，但是是空的，你运行MR的时候会对应重新创建  所以你担心的filecache删除了后面解决不了会不会有影响  不放心的话，你给他备份一样，你重启之后还是没有的 除非你不放在这个目录

重启yarn之后解决  ！
