I install openstack icehouse, then install sahara. I create cluster, it<br>
worked!<br>
But when i login master-instance, test. Run `hadoop jar<br>
hadoop-examples-1.2.1.jar pi 10 100` ==> Message error:<br>
`java.io.IOException: Cannot create input directory<br>
PiEstimator_TMP_3_141592654/<u></u>in...`<br>
<br>
I check service hadoop-namenode, it's not working. Message:<br>
`start-stop-daemon: unable to set gid to 201 (Operation not permitted)`. All<br>
service hadoop-* not working, too.<br>
<br>
Go back, i check log, have warning. Summarize:<br>
<br>

(reason: 'NoneType' object has no attribute 'node_groups')<br>

<br>
I use:<br>
<br>
- Plugin Vanilla 1.2.1<br>
- Hadoop version 1.2.1<br>
- Image: sahara-icehouse-vanilla-1.2.1-<u></u>ubuntu-13.10.qcow2<br>

<br>
Details steps i created cluster:<br>

<br>
I think: I failed step config sahara or create node template? Because<br>
service sahara not running, so hadoop not worked :(<br>
Can you help me? Thanks!<br>
