Not able to access cinder api,

When took a look at /usr/lib/python2.7/dist-packages/cinder/i18n.py, found that _LE is missing over here.

import oslo_i18n as i18n

DOMAIN = 'cinder'

_translators = i18n.TranslatorFactory(domain=DOMAIN)

# The primary translation function using the well-known name "_"
_ = _translators.primary

def enable_lazy(enable=True):
    return i18n.enable_lazy(enable)

def translate(value, user_locale=None):
    return i18n.translate(value, user_locale)

def get_available_languages():
    return i18n.get_available_languages(DOMAIN)

Hello Noopur,

Thank you for taking time to report this issue. It appears that the version of /usr/lib/python2.7/dist-packages/cinder/exception.py that you have is from Ocata. Can you please paste the results of 'dpkg -l | grep cinder' to the bug?

Thanks,
Corey

Hi Corey, We are also facing the same issue pasting here the requested result:

Hi Akshay,

I'm unable to recreate this, unfortunately. Are there any more details that you can share to help me reproduce this?

The following line of code in cinder/exception.py changed from this in ocata:
  from cinder.i18n import _, _LE
to this in pike:
  from cinder.i18n import _

And the following line of code in cinder/i18n.py existed in ocata but was removed in pike:
  _LE = _translators.log_error

I just tested an install of cinder-api from ocata, that I then upgraded to pike, these files are updated correctly as described above.

Is there any chance that you had an upgrade from ocata->pike that failed?

Thanks,
Corey
