StackdriverExporter with application default credentials crashes #304
Description
I noticed that currently, if we're using the application default credentials, the StackdriverExporter ends up crashing because of this issue in google-auth-library-python and the only way to make it work again is to restart the background thread.
The tracing collection goes fine for a while, and then starts failing in loops with:
...
File "/usr/local/lib/python2.7/dist-packages/google/cloud/client.py", line 212, in __init__
Client.__init__(self, credentials=credentials, _http=_http)
File "/usr/local/lib/python2.7/dist-packages/google/cloud/client.py", line 125, in __init__
credentials, _ = google.auth.default()
File "/usr/local/lib/python2.7/dist-packages/google/auth/_default.py", line 286, in default
raise exceptions.DefaultCredentialsError(_HELP_MESSAGE)
DefaultCredentialsError: Could not automatically determine credentials. Please set GOOGLE_APPLICATION_CREDENTIALS or
explicitly create credential and re-run the application. For more
