"UnicodeDecodeError: 'ascii' codec can't decode" during job-binary-internals request to Sahara-api

[Leontii Istomin]

During pi_job_vanilla_7_0 rally scenario which creates Sahara cluster and calculates pi number using created hadoop we faced with the following error:
from rally.log: http://paste.openstack.org/show/473516/
It seems it happened during job-binary-internals request:
from rally.log: http://paste.openstack.org/show/473517/
from sahara-api: http://paste.openstack.org/show/473518/

It seems data should be logged, but can't because it includes some binary data.

[Evgeny Sikachev (esikachev)]

This is keystoneclient bug. Because, binary request can not read in log. Workaround: disable debug-log in keystone

[Boris Bobrov (bbobrov)]

Upstream bug is assigned to Nikita Konovalov https://bugs.launchpad.net/python-keystoneclient/+bug/1453953 and a fix was proposed. Since this is a medium bug, I would like to wait more for the fix to get to upstream.

[Boris Bobrov (bbobrov)]

The patch was unassigned since the patch is abandoned. I'll pick it up a now.

[Davanum Srinivas (DIMS) (dims-v)]

Added a note in upstream bug about using oslo.utils' encodeutils.safe_encode

[Boris Bobrov (bbobrov)]
