Hi, I am using openstack grizzly.
I just commented out [pipeline:openstack_compute_api_v2] pipeline = faultwrap authtoken keystonecontext ratelimit osapi_compute_app_v2 [pipeline:openstack_volume_api_v1] pipeline = faultwrap authtoken keystonecontext ratelimit osapi_volume_app_v1 and its working good. Thanks a lot.

(HTTP 413) Hmm, not sure, I am not an expert in Nova. By the way the link I gave you is for Grizzly. If you are running a different release, take a look at that release doc as configuration might look different here.

(HTTP 413) Hello Arindam, While deploying Hadoop cluster Savanna does pretty many API requests to Nova. Naturally, the number of requests is directly proportional to the size of the cluster. On the other hand Nova has a protection agains users abusing API with too many requests. It is called rate limiting. You need to set limits higher than they are right now if you want to spin-up a cluster of that size. You can find details in the Nova docs: http://docs.openstack.org/grizzly/openstack-compute/admin/content//configuring-compute-API.html Dmitry 2013/12/5 Arindam Choudhury <arin...@live.com> Hi, When I try to create a big hadoop cluster (21 nodes), sometimes I am getting this error: 2013-12-05 12:17:57.920 29553 ERROR savanna.context [-] Thread 'cluster-creating-8d093d9b-c675-4222-b53a-3319d54bc61f' fails with exception: 'This request was rate-limited.
