Yulei Li commented on HDFS-10863:
---------------------------------
According to your setup, I found my linux user matched hdfs:
[hadoop@hadoop ~]$ ll test
-rw-rw-r--. 1 hadoop hadoop 5 9月 20 14:25 test
[hadoop@hadoop ~]$ hdfs dfs -ls /tmp
Found 1 items
-rw-r--r-- 1 hadoop hadoop 5 2016-09-20 14:30 /tmp/test
My OS is CentOS7, and hadoop version is hadoop 3.0.0, I don't think it is a
bug. Could you show some more information about your environment and
configuration?

> Key: HDFS-10863
> URL: https://issues.apache.org/jira/browse/HDFS-10863
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 2.7.2
> Environment: $ hadoop version
> Hadoop 2.7.2
> Reporter: www.jbigdata.fr
> Priority: Minor
>
> I want to match my unix user to HDFS: hduser:hadoop.
> For the user I use the VE.
> $ echo $HADOOP_HDFS_USER
> hduser
> For the group I use the hdfs-site.xml :
> <property>
> <name>dfs.permissions.superusergroup</name>
> <value>hadoop</value>
> </property>
> The namenode log file show the parameter user/group values.
> INFO org.apache.hadoop.hdfs.server.namenode.FSNamesystem: fsOwner
> = hduser (auth:SIMPLE)
> INFO org.apache.hadoop.hdfs.server.namenode.FSNamesystem: supergroup
> = hadoop
> INFO org.apache.hadoop.hdfs.server.namenode.FSNamesystem: isPermissionEnabled
> = true
> Everything seems to be OK, but when I copy file form FS to HDFS the group is
> not correct. It keeps the supergroup default value.
> Thoses shell commands show the issue:
> $ ll /srv/downloads/zk.tar
> -rw-r--r-- 1 hduser hadoop 41984000 Aug 18 13:25 /srv/downloads/zk.tar
> $ hdfs dfs -put /srv/downloads/zk.tar /tmp
> $ hdfs dfs -ls /tmp/zk.tar
> -rw-r--r-- 2 hduser supergroup 41984000 2016-09-14 12:47 /tmp/zk.tar
> I have:
> -rw-r--r-- 2 hduser supergroup 41984000 2016-09-14 12:47 /tmp/zk.tar
> I expect :
> -rw-r--r-- 2 hduser hadoop 41984000 2016-09-14 12:47 /tmp/zk.tar
> Why the HDFS group is not the value of the dfs.permissions.superusergroup
> property ?
