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. ERROR root [-] Original exception being dropped: ['Traceback (most recent call last):\n', ' File "/home/bkcloud/sahara-venv/local/lib/python2.7/site-packages/sahara/service/direct_engine.py", line 65, in create_cluster\n volumes.attach(cluster)\n', ' File "/home/bkcloud/sahara-venv/local/lib/python2.7/site-packages/sahara/service/volumes.py", line 31, in attach\n for node_group in cluster.node_groups:\n', "AttributeError: 'NoneType' object has no attribute 'node_groups'\n"] ERROR sahara.context [-] Thread 'cluster-creating-91420b4b-9e89-44ff-8ce4-6cd5740e7bdc' fails with exception: 'Cluster id 'None' not found!' Can you help me? Thanks!
