Add support for kerberos

laserson commented 9 years ago

This may need a bit of refactoring to deal with the request objects correctly.

Any updates on adding Kerberos support?

Thooms commented 8 years ago

I'm using pywebhdfs and kerberos, and a neat solution (that requires an additionnal dependency) is to use https://github.com/requests/requests-kerberos, that works out of the box. Here is an exemple:

from requests_kerberos import HTTPKerberosAuth
from pywebhdfs.webhdfs import PyWebHdfsClient

auth = HTTPKerberosAuth()
hdfs_client = PyWebHdfsClient(request_extra_opts={'auth':auth})

# then use the client as usual

This obviously assumes that you have a correct Kerberos setup on the machine.

Hi @Thooms, Thanks for sharing this one. I tried this one (on Linux machine), but facing error "ImportError: No module named win32security" I'm new to python, can you please suggest how we can fix the issue? Appreciate your help!

instead of >>> from requests_kerberos import HTTPKerberosAuth try >>> import kerberos then you can see another error message more useful. Instead of running on win32 system, I added LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib64 for kerberos. Because the error message of running 'import kerberos' was ImportError: /venv_path/lib/python2.7/site-packages/kerberos.so: symbol gss_wrap_iov, version gssapi_krb5_2_MIT not defined in file libgssapi_krb5.so.2 with link time reference

HTTPKerberosAuth is NOT only for win32.
