[openstack-dev] [Sahara] Master-instance: Service hadoop-* not running

2014-07-14 Thread Dat Tran 
 Hi everybody,

I install openstack icehouse, then install sahara. I create cluster, it
worked!
But when i login master-instance, test. Run hadoop jar
hadoop-examples-1.2.1.jar pi 10 100
== Message error: java.io.IOException: Cannot create input directory
PiEstimator_TMP_3_141592654/in...


 I check service hadoop-namenode, it's not working.

==Message: start-stop-daemon: unable to set gid to 201 (Operation not
permitted).

All service hadoop-* not working, too.


 Go back, i check log, have warning. Summarize:
WARNING sahara.service.engine [-] Can't start cluster '_unknown_' (reason:
'NoneType' object has no attribute 'node_groups')
WARNING sahara.service.engine [-] Presumably the operation failed because
the cluster wasdeleted by a user during the process.

Can you help me? Thanks!

 This is the wrong list to report problems while using openstack.

 use openstack-dev only to discuss the future of OpenStack, even if you
 area a developer.

 Post this question on openst...@lists.openstack.org or
 https://ask.openstack.org (after you've searched to see if there are
 answers already).

 thanks,
 stef

[openstack-dev] Mahout-as-a-service

2014-05-28 Thread Dat Tran 
Hi everyone,

I have a idea for new project: Mahout-as-a-service.
Main idea of this project:
- Install OpenStack
- Deploying OpenStack Sahara source
- Deploying Mahout on Sahara OpenStack system.
- Construction of the API.

Through web or mobile interface, users can:
- Enable / Disable Mahout on Hadoop cluster
- Run Mahout job
- Get information on surveillance systems related to Mahout job.
- Statistics and service costs over time and total resource use.

Definitely!!! APIs will be public. Look forward to your comments. Hopefully
in this summer, we can do something together.

Thank you very much! :)
