Comment 0 for bug 1498520

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.

Cluster configuration:
Baremetal,Ubuntu,IBP,HA, Neutron-vxlan,Ceph-all,Nova-debug,Nova-quotas,Sahara,7.0-296
