The user who started the NN has superuser privileges on HDFS.
You can also configure a supergroup by setting
dfs.permissions.supergroup (default "supergroup")

Hi,
"hadoop" user has some advantages for running Hadoop. For example, if HDFS
is mounted as a local file system, then only user "hadoop" has write/delete
permissions.
Can this privilege be given to another user? In other words, is this
"hadoop" user hard-coded, or can another be used in its stead?
Thank you,
Mark
You may also set dfs.permissions = false and grant seperate groups to
access HDFS through properties in hdfs.sites.xml
