Review request for ranger, Ankita Sinha, bhavik patel, Gautam Borad, and Ramesh
Mani.
Bugs: RANGER-2671
https://issues.apache.org/jira/browse/RANGER-2671
Repository: ranger
Description
-------
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
```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)
```
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.
