---------------------------------------------
Summary: Failed to list clusters due to NPE at
createClusterResponse(ApiResponseHelper.java:837)
Key: CLOUDSTACK-1551
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1551
Project: CloudStack
Issue Type: Bug

aa40c7ee98b36370069effb68388ba751d7dc6e5
Steps to reproduce (faced on the fresh setup):
1) Added zone, pod and new cluster.
2) Added new host to the cluster
3) Tried to add storage pool to the cluster, but it failed (incorrect mount
path was specified in the API)
After that listCluster command resulted in NPE:

NPE happened because api layer tries to retrieve cluster details assuming that
they are always in cluster_details table.
