Description

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

OOZIE_SERVER

Indicators

• Command JSON
  • config['configurations']['cluster-env']['security_enabled']
    • = “true”
• Configuration File: params.conf_dir + ‘/oozie-site.xml’
  • oozie.service.AuthorizationService.security.enabled
    • = “true”
    • required
  • oozie.service.HadoopAccessorService.kerberos.enabled
    • = “true”
    • required
  • local.realm
    • not empty
    • required
  • oozie.authentication.type
    • = “kerberos”
    • required
  • oozie.authentication.kerberos.principal
    • not empty
    • required
  • oozie.authentication.kerberos.keytab
    • not empty
    • path exists and is readable
    • required
  • oozie.authentication.kerberos.name.rules
    • not empty
    • required
  • oozie.service.HadoopAccessorService.keytab.file
    • not empty
    • path exists and is readable
    • required
  • oozie.service.HadoopAccessorService.kerberos.principal
    • not empty
    • required

Pseudocode

if indicators imply security is on and validate
    if kinit(oozie principal) && kinit(HadoopAccessorService 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
