6:35 a.m.
I've got VMs up and running :-
[root@ServerCentOS7 ~(keystone_admin)]# nova list
+--------------------------------------+------------------------------------+--------+------------+-------------+----------------------------------+
| ID | Name | Status |
Task State | Power State | Networks |
+--------------------------------------+------------------------------------+--------+------------+-------------+----------------------------------+
| fccee6b5-af62-4008-b12b-5966dcf56bd6 | demo-cluster1-hadoop-master-node-0 | ACTIVE | -
| Running | private=50.0.0.17, 192.168.1.157 |
| e9bbf603-5eb9-45ff-8375-f583742720bf | demo-cluster1-hadoop-work-node-0 | ACTIVE | -
| Running | private=50.0.0.16, 192.168.1.156 |
+--------------------------------------+------------------------------------+--------+------------+-------------+----------------------------------+
But when I logged into any of them `java -version` reports that java is not installed.
Looks like I am supposed set up 2 Node Hadoop Cluster manually.
Thanks.
Boris

Subject: [Rdo-list] Failure to launch Hadoop Cluster via Sahara Wizards on RDO
Liberty
Daemons to run on VMs generated via heat templates hadoop-master-node and

configured following :-
[root@ServerCentOS7 2.6.0]# cat node_group_template_master.json

Spawning of Cluster ends up with errors in sahara-api.log :-

In heat-engine.log I see :-

and so . Bunch of imports is failing.
I woul also expect path
/usr/lib/python2.7/site-packages/sahara/tests/scenario/templates/vanilla/2.6.0 to finish
with 2.7.1
Attempt to generate Custer based on Hadoop Vanilla plugin 2.6.0 gets rejected right
away.
Please, advise
Boris.
