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.

Specified by:

execute in interface ServerAction

Overrides:

execute in class PrepareKerberosIdentitiesServerAction

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

processIdentity

protected CommandReport processIdentity(ResolvedKerberosPrincipal resolvedPrincipal,
                                        KerberosOperationHandler operationHandler,
                                        Map<String,String> kerberosConfiguration,
                                        boolean includedInFilter,
                                        Map<String,Object> requestSharedDataContext)
                                 throws org.apache.ambari.server.AmbariException

Description copied from class: KerberosServerAction

Processes an identity as necessary.

This method is called from KerberosServerAction.processIdentities(Map) for each principal found by specified filter. After processing, it is expected that the return value is null on success and a CommandReport (indicating the error) on failure.

Overrides:

processIdentity in class AbstractPrepareKerberosServerAction

Parameters:

resolvedPrincipal - a ResolvedKerberosPrincipal object to process

operationHandler - a KerberosOperationHandler used to perform Kerberos-related tasks for specific Kerberos implementations (MIT, Active Directory, etc...)

kerberosConfiguration - a Map of configuration properties from kerberos-env

includedInFilter - a Boolean value indicating whather the principal is included in the current filter or not

requestSharedDataContext - a Map to be used a shared data among all ServerActions related to a given request @return a CommandReport, indicating an error condition; or null, indicating a success condition

Throws:

org.apache.ambari.server.AmbariException - if an error occurs while processing the identity record
