Ignasi Barrera commented on JCLOUDS-1444:
-----------------------------------------
As a workaround you can configure the {{jclouds regions}} property with the
list of regions you want to use and jclouds should only hit those regions.
> Outage on any endpoint in catalog blocks usage of other endpoints

> Key: JCLOUDS-1444
> URL: https://issues.apache.org/jira/browse/JCLOUDS-1444
> Project: jclouds
> Issue Type: Bug
> Components: jclouds-compute
> Affects Versions: 2.1.1
> Environment: OVH OpenStack
> Reporter: Gilles Coremans
> Priority: Major
> Labels: NovaComputeService, openstack, openstack-nova
>
> I was trying to create a template using the ComputeService backed by the nova
> API (I was connecting to OVH, which does not have a jClouds provider).
> However, one of their regions was down for maintenance. This caused the
> following error:
> {code:java}
> SEVERE: Cannot retry after server error, command has exceeded retry limit 5:
> [method=org.jclouds.openstack.nova.v2_0.features.ImageApi.public abstract
> org.jclouds.collect.PagedIterable
> org.jclouds.openstack.nova.v2_0.features.ImageApi.listInDetail()[],
> request=GET https://compute.bhs3.cloud.ovh.net/v2/[tenant]/images/detail
> HTTP/1.1{code}
> I feel that jClouds shold handle this case gracefully and simply skip the
> offending API, rather than failing with NullPointerExceptions and making it
> impossible to create templates as long as any endpoint is down for whatever
> reason.
> This is the reply one gets when querying the given URL directly:
> {code:java}
> $ curl https://compute.bhs3.cloud.ovh.net/v2/[tenant]/images/detail
> curl: (52) Empty reply from server
> {code}
> I verified on OVH's site that this region was indeed down for maintenance:
