hi,Gowri, no matter which question you encoutered, from the log it should be your savanna server can't ssh to that vm(name node or data node). now ,have you fix these problem?

Hi Andrew Lazarev,

As per your suggestion, I used VM image centos-6_64-hdp-1.3.qcow2 from [link : http://savanna.readthedocs.org/en/latest/userdoc/hdp_plugin.html] (http://savanna.readthedocs.org/en/lat...) .

The VM instances are in ACTIVE state, I can ping and SSH into them .But the cluster is in 'configuring' state from one day.

I used centos-6_64-hdp-1.3.qcow2 image . The savanna logs is as follows:

savanna.plugins.hdp.versions.1_3_2.versionhandler [-] Waiting to connect to ambari server ... 2014-02-10 04:24:21.703 19754 INFO savanna.plugins.hdp.versions.1_3_2.versionhandler [-] Waiting to connect to ambari server ... 2014-02-10 04:24:26.707 19754 INFO urllib3.connectionpool [-] Starting new HTTP connection (1): 172.16.8.28 2014-02-10 04:24:26.708 19754 INFO urllib3.connectionpool [-] Starting new HTTP connection (1): 172.16.8.28 2014-02-10 04:24:26.709 19754 INFO savanna.plugins.hdp.versions.1_3_2.versionhandler [-] Waiting to connect to ambari server ... 2014-02-10 04:24:26.709 19754 INFO savanna.plugins.hdp.versions.1_3_2.versionhandler [-] Waiting to connect to ambari server ...

I found this information from https://bugs.launchpad.net/savanna/+bug/1259836 (https://bugs.launchpad.net/savanna/+b...) that the latest HDP vm image should resolve this issue .But I am still facing this problem.

What could be the problem ? please help.

1. "Can't start cluster 'ostf-test-savanna-cluster' (reason: node ostf-test-savanna-cluster-ostf-test-worker-node-tt-dn-001 has error status)" This means that instance didn't appear in 'active' state. You should check openstack logs on the reason.

2. "'RemoteCommandException: Error during command execution: "sudo chown -R $USER:$USER /etc/hadoop"" I see you are using vanilla plugin while both images you listed are for HDP plugin. Please use only images supported by plugin you use.

Hi Gowri,

Could you please provide savanna stacktrace on this error?

i encounter the same problem,sometimes start cluster successfully displaying active,sometimes display "File "/opt/stack/savanna/local/lib/python2.7/site-packages/eventlet/greenio.py", line 46, in socket_checkerr raise socket.error(err, errno.errorcode[err]) error: [Errno 111] ECONNREFUSED"

can someone know whether this is a bug?

You don't need to add this argument. virtual environment prevents conflicts with existing python packages installed on your system.

you also can install savanna on a in your system path using the following command: $ pip install savanna

Hello jianfeng2013,

Did you install Savanna in a separate python virtual environment? In order to do that run: "cd ~; virtualenv savanna-venv" This will install new virtual environment into savanna-venv directory in your home directory.

Then you can install Savanna inside this virtual environment: "savanna-venv/bin/pip install savanna" (for more information please visit http://savanna.readthedocs.org/en/latest/userdoc/installation.guide.html (http://savanna.readthedocs.org/en/lat...) )

After that try to create cluster again

Hi gws, I am having a similar situation, I am using Mirantis Fuel 4.0, I used image[centos-6-64-hdp-vanilla.qcow2 ] from [link : http://savanna.readthedocs.org/en/latest/userdoc/hdp_plugin.html] (http://savanna.readthedocs.org/en/lat...) . The inastances are up and I can SSH and ping them but the cluster turns into erroe state .

Savanna logs have something like ' failed execution chown $USER:$USER /etc/hadoop ,RuntimeError : node newcluster_vanilla_worker-001 has error status '.

Do you have any idea about this? I am stuck with this for quite some time :(.Since I am using Fuel installer, it is supposed to take care of all configuration after ti launch cluster using a registered image.Any help is appreciated.

Thanks.
