Hi all,

When trying to create a new Hadoop Cluster using Sahara in OpenStack, we ended up by the following debug error trace in sahara api log file:

2015-10-05 06:31:18.917 3139 ERROR sahara.context [-] Thread 'attach-volumes-for-instance Hadoop-Cluster Hadoop-Master-Node-001' fails with exception: 'Error attach volume to instance Hadoop-Cluster-Hadoop-Master-Node-001'
2015-10-05 06:31:18.953 3139 ERROR sahara.context [-] Thread 'attach-volumes-for-ng-Hadoop-Master-Node' fails with exception: 'An error occurred in thread 'attach-volumes-for-instance-Hadoop-Cluster-Hadoop-Master-Node-001': Error attach volume to instance Hadoop-Cluster-Hadoop-Master-Node-001'

What looks strange that the templates both in Master and Worker nodes have not been configured to use cinder volumes and they suppose to create ephemeral disks as default storage option.

The Implementation is configured to create a Hadoop Cluster within Vanilla 2.3.0 in Icehouse release (RDO installation) The status of the cluster in Sahara is looping on 'Waiting' status and finished by Error. Image used is ubuntu vanilla from Mirantis sahara file repository with a medium flavor per instance (2 VCPUs, 40 GB Disk and 4 GB RAM)

Googling was not really helping this time. Does anyone has faced such error in Sahara ?

Thanks in advance !
