lost gssapi.raw.ext_cred_store module

[shm007g]

when i use krbContext to download hdfs files in yarn cluster as below:

with krbContext(using_keytab=True, principal=principal, keytab_file=keytab_path):
            client = KerberosClient('http://{0}:50070'.format(server))
            client.download(os.path.join(HDFS_ROOT, hdfs_path), local_path, overwrite=True)

error happens here:

 with krbContext(using_keytab=True, principal=principal, keytab_file=keytab_path):
  File "/usr/local/anaconda3/lib/python3.5/site-packages/krbcontext/context.py", line 281, in __enter__
    self._prepare_context()

    self.init_with_keytab()

    creds = gssapi.creds.Credentials(**creds_opts)

    raise NotImplementedError("Your GSSAPI implementation does "
NotImplementedError: Your GSSAPI implementation does not have support for manipulating credential stores

then i google it, i found this in gssapi code then i search for rcred_cred_store then i search for import_gssapi_extension

OMG, lost one module!!!

>>> import gssapi
>>> import gssapi.raw
>>> import gssapi.raw.ext_cred_store
Traceback (most recent call last):

What version of python-gssapi are you using?

[tkdchen]

Both latest version gssapi 1.5.1 and python2-gssapi-1.3.0-1.fc27.x86_64 work well with import gssapi.raw.ext_cred_store.
