Thanks for your review @tomscut , actually `chown ` command can be used for
change owner or group belong info.
i used chown to change the file group ,keeping the owner as the before.
maybe we can make it clearer ,if we use `chown` to change owner ,super user
is a must, if we use `chown` to change the group ,then user either may be the
owner of the files or the super user.
reproduce steps as the following
step1 :create new group
`groupadd philipse1`
step2:add user to the group
`useradd philipse -g philipse1`
step3: touch a file(any user)
hdfs dfs -touch /tmp/test2/test3
step4:use super user(hadoop is the super user) to change the owner and group
of the file to philipse
hdfs dfs -chown philipse:philipse /tmp/test2/test3
now we get the file info as the following:
`-rw-r--r
