Method Detail

execute

public CommandReport execute(ConcurrentMap<String,Object> requestSharedDataContext)
                      throws org.apache.ambari.server.AmbariException,
                             InterruptedException

Called to execute this action. Upon invocation, calls KerberosServerAction.processIdentities(Map) to iterate through the Kerberos identity metadata and call KerberosServerAction.processIdentities(Map) for each identity to process.

Parameters:

requestSharedDataContext - a Map to be used a shared data among all ServerActions related to a given request

Returns:

a CommandReport indicating the result of this action

Throws:

org.apache.ambari.server.AmbariException

InterruptedException

getKerberosDescriptor

protected KerberosDescriptor getKerberosDescriptor(Cluster cluster,
                                                   boolean includePreconfigureData)
                                            throws org.apache.ambari.server.AmbariException

Calls KerberosHelper.getKerberosDescriptor(Cluster, boolean)

Parameters:

cluster - cluster instance

includePreconfigureData - true to include the preconfigure data; false otherwise

Returns:

the kerberos descriptor associated with the specified cluster

Throws:

org.apache.ambari.server.AmbariException - if unable to obtain the descriptor
