getCommonLauncherClasses

getLauncherClasses

initActionType

public void initActionType()

Description copied from class: ActionExecutor

Invoked once at system initialization time.

It can be used to register error information for the expected exceptions. Exceptions should be register from subclasses to superclasses to ensure proper detection, same thing that it is done in a normal catch.

This method should invoke the ActionExecutor.registerError(java.lang.String, org.apache.oozie.action.ActionExecutorException.ErrorType, java.lang.String) method to register all its possible errors.

Subclasses overriding must invoke super.

Overrides:

Returns:

maximum size of stats

requiresNameNodeJobTracker

public boolean requiresNameNodeJobTracker()

Description copied from class: ActionExecutor

Returns true if this action type requires a NameNode and JobTracker. These can either be specified directly in the action via <name-node> and <job-tracker>, from the fields in the global section, or from their default values. If false, Oozie won't ensure (i.e. won't throw an Exception if non-existant) that this action type has these values.

Overrides:

requiresNameNodeJobTracker in class ActionExecutor

Returns:

true if a NameNode and JobTracker are required; false if not

supportsConfigurationJobXML

public boolean supportsConfigurationJobXML()

Description copied from class: ActionExecutor

Returns true if this action type supports a Configuration and JobXML. In this case, Oozie will include the <configuration> and <job-xml> elements from the global section (if provided) with the action. If false, Oozie won't add these.

Overrides:

supportsConfigurationJobXML in class ActionExecutor

Returns:

true if the global section's Configuration and JobXML should be given; false if not
