Method Detail

handleBeanRun

protected ExitStatus handleBeanRun(YarnClient bean,
                       java.lang.String[] parameters,
                       java.util.Set<java.lang.String> opts)

Description copied from class: AbstractCommandLineRunner

Handles the execution of a bean after Application Context(s) has been initialized. This is considered to be a main entry point what the application will do after initialization.

It is implementors responsibility to decide what to do with the given bean since this class only knows the typed bean instance.

Specified by:

handleBeanRun in class AbstractCommandLineRunner<YarnClient>

Parameters:

bean - the bean instance

parameters - the parameters

opts - the options

Returns:

the exit status

getDefaultBeanIdentifier

protected java.lang.String getDefaultBeanIdentifier()

Description copied from class: AbstractCommandLineRunner

Gets a default bean id which is used to resolve the instance from an Application Context.

Specified by:

getDefaultBeanIdentifier in class AbstractCommandLineRunner<YarnClient>

Returns:

the id of the bean

getValidOpts

protected java.util.List<java.lang.String> getValidOpts()

Description copied from class: AbstractCommandLineRunner

Gets the list of valid option arguments. Default implementation returns null thus not allowing any options exist on a command line.

When overriding valid options make sure that options doesn't match anything else planned to be used in a command line. i.e. usually it's advised to prefix options with '-' character.

Overrides:

getValidOpts in class AbstractCommandLineRunner<YarnClient>

Returns:

the list of option arguments

queryApplicationId

protected org.apache.hadoop.yarn.api.records.ApplicationId queryApplicationId(YarnClient client,
                                                                  java.lang.String applicationId)

Query application id.

Parameters:

client - the yarn client

applicationId - the application id

Returns:

the application id if exists, NULL otherwise
