    Description

      Cluster configuration:

      • 3 Master nodes
      • Existing MIT KDC local to the cluster
      • sles11sp3

      While enabling Kerberos via Ambari's Enable Kerberos Wizard the Mahout Service Check is failing during the last step of the Wizard "Start and Test All Services".

      Output from the failed Check Mahout operation:

      stderr:
