Falcon service components should indicate security state

    Details

      Description

      The Falcon service components should indicate security state when queried by Ambari Agent via STATUS_COMMAND. Each component should determine it's state as follows:

      FALCON_CLIENT

      Indicators

      • Command JSON
        • config['configurations']['cluster-env']['security_enabled']
          • = “true”

      PseudoCode

      if indicators imply security is on and validate
          state = SECURED_KERBEROS
      else
          state = UNSECURED
      

      FALCON_SERVER

      Indicators

      • Command JSON
        • config['configurations']['cluster-env']['security_enabled']
          • = “true”
      • Configuration File: params.falcon_conf_dir + ‘/startup.properties’
        • *.falcon.authentication.type
          • = “kerberos”
        • *.falcon.service.authentication.kerberos.principal
          • not empty
          • required
        • *.falcon.service.authentication.kerberos.keytab
          • not empty
          • required
          • path exists and is readable
        • *.dfs.namenode.kerberos.principal
          • not empty
          • required
        • *.falcon.http.authentication.type
          • = “kerberos”
        • *.falcon.http.authentication.kerberos.principal
          • not empty
          • required
        • *.falcon.http.authentication.kerberos.keytab
          • not empty
          • required
          • path exists and is readable

      Pseudocode

       
      if indicators imply security is on and validate
          if kinit(falcon principal) && kinit(http principal) succeeds
              state = SECURED_KERBEROS
          else
              state = ERROR 
      else
          state = UNSECURED
      

      Note: Due to the cost of calling kinit results should be cached for a period of time before retrying. This may be an issue depending on the frequency of the heartbeat timeout.
      Note: kinit calls should specify a temporary cache file which should be destroyed after command is executed - BUG-29477
