security.UserGroupInformation：MR的PriviledgedActionException错误 [英] security.UserGroupInformation: PriviledgedActionException error for MR

问题描述

无论何时我试图执行映射reduce作业来写入Hbase表，我在控制台中收到以下错误。我从用户帐户运行MR作业。

错误security.UserGroupInformation：PriviledgedActionException as：user cause：org.apache.hadoop.mapreduce.lib.input.InvalidInputException ：输入路径不存在：file：/data1/input/Filename.csv

我做过hadoop ls，用户是文件的所有者。

-rw-r - r-- 1个用户超级组7998682 2014-04-17 18:49 /data1/input/Filename.csv

我的所有守护进程都正常运行，如果我使用的是hbase client api，我可以插入。

请提前帮助， p>

感谢，

解决方案

以下路径

输入路径不存在： file： /data1/input/Filename.csv

你可以看到它指向的是本地文件系统而不是hdfs。尝试在路径中为文件系统类型hdfs加上前缀：

  hdfs：//< NAMENODE-HOST>：< IPC- PORT> /data1/input/Filename.csv 
  

Whenever i m trying to execute a map reduce job to write to Hbase table i am getting the following error in the console. I am running the MR job from the user account.

ERROR security.UserGroupInformation: PriviledgedActionException as:user cause:org.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does not exist: file:/data1/input/Filename.csv

I did the hadoop ls, user is the owner of the file.

-rw-r--r-- 1 user supergroup 7998682 2014-04-17 18:49 /data1/input/Filename.csv

All my daemons are perfectly running, if i am using hbase client api, i am able to insert.

Please help, thanks in advance.

Thanks, KG

解决方案

If you look at the following path

Input path does not exist: file:/data1/input/Filename.csv

you can see that it is pointing to local filesystem not to hdfs. Try prefixing the filesystem type hdfs in the path as follows

hdfs://<NAMENODE-HOST>:<IPC-PORT>/data1/input/Filename.csv
