Ambari cluster installation failed: status code received on DELETE method for API: /api/v1/clusters/Mead

Hi,

i tried an installation of the cluster with Ambari. The first try registrated all ambari-agent but failed to install the services cause of an JDK problem. The only complete service was the namenode Service on the Isilon Cluster (nn-hdp.mead.mobilcom.de).

After fixing the JDK problems the next try failed deploying the Cluster with the Error message: org.apache.ambari.server.controller.spi.SystemException: An internal system exception occurred: Could not delete cluster, clusterName=Mead.

ambari-server.log:
