Akira AJISAKA commented on HDFS-6761:
-------------------------------------
JIRA is to track bug reports, not for end-user questions.

When i use 'testuser' account, I try to 'hadoop fs mkdir /user/data' command.
I think 'hadoop fs mkdir /user/data' command not working.

Probably the old user-to-group mapping had been cached, so the command failed.
You can execute "hdfs dfsadmin -refreshUserToGroupsMappings" to clean up the
cache.
If you have a question, please send an e-mail to [email protected].
