Re: hdfs : Change supergroup

[Francis Dupin]

Thank you.

I think my problem was here :

When a file or directory is created, its owner is the user identity of 
the client process, and its group is the group of the parent directory 
(the BSD rule).

Dear all,

Concern Hadoop 2.6.0

When I create a file as superuser, the group owner is 99.


But I have created a user:group for the superuser : hadoop:hadoop
(1003)
and added in hdfs-site.xml :



dfs.permissions.supergroup
hadoop

The name of the group of super-users



Restarted all ... No change :
Files created are owned by hadoop:99 and in the webUI I can read
"hadoop:supergroup"


Any idea ?

Thank you
