> If we run setup.sh in usersync a second time, the setup.py in usersync folder
> will change the permissions to 0750 and owner to ranger:ranger of hadoop
> core-site.xml. This will affect other software that needs to read
> core-site.xml, for example, hiveserver2 will fail to start because it does
> not have permission to read core-site.xml. Ranger should never change the
> permission or ownership of core-site.xml in hadoop conf dir.
> The reason why the permissions and owner of core-site.xml are modified is
> because the following code in unixauthservice/scripts/setup.py
> {code:python}
> for dir in fixPermList:
> for root, dirs, files in os.walk(dir):
> os.chown(root, ownerId, groupId)
> os.chmod(root, 0755)
> for obj in dirs:
> dn = join(root, obj)
> os.chown(dn, ownerId, groupId)
> os.chmod(dn, 0755)
> for obj in files:
> fn = join(root, obj)
> os.chown(fn, ownerId, groupId)
> os.chmod(fn, 0750)
> {code}
> If we run setup.sh in usersync a second time, there will be a soft link of
> core-site.xml in /etc/ranger/usersync/conf. In the for loop, it will traverse
> to /etc/ranger/usersync/conf/core-site.xml, and use os.chown and os.chmod to
> change the permisson and ownership. We should unlink the soft link of
> core-site.xml before this for loop.
