hdfs : Change supergroup
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 :
<property>
<name>dfs.permissions.supergroup</name>
<value>hadoop</value>
<description>
The name of the group of super-users
</description>
</property>
Restarted all ... No change :
Files created are owned by hadoop:99 and in the webUI I can read
"hadoop:supergroup"
Any idea ?
Thank you

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).

Changing the supergroup configuration would not affect the existing group
maintained on the file inodes (its persisted since the beginning, not
pulled dynamically from config at every restart). You will need to manually
fs -chgrp those.
