Method Detail

getLauncherClasses

protected List<Class> getLauncherClasses()

Overrides:

getLauncherClasses in class JavaActionExecutor

getLauncherMain

protected String getLauncherMain(org.apache.hadoop.conf.Configuration launcherConf,
                                 org.jdom.Element actionXml)

Overrides:

getLauncherMain in class JavaActionExecutor

end

public void end(ActionExecutor.Context context,
                org.apache.oozie.client.WorkflowAction action)
         throws ActionExecutorException

We will gather counters from all executed action Hadoop jobs (e.g. jobs that moved data, not the launcher itself) and merge them together. There will be only one job most of the time. The only exception is import-all-table option that will execute one job per one exported table.

Overrides:

end in class JavaActionExecutor

Parameters:

context - Action context

action - Workflow action

Throws:

ActionExecutorException

getActionData

protected void getActionData(org.apache.hadoop.fs.FileSystem actionFs,
                             org.apache.hadoop.mapred.RunningJob runningJob,
                             org.apache.oozie.client.WorkflowAction action,
                             ActionExecutor.Context context)
                      throws HadoopAccessorException,
                             org.jdom.JDOMException,
                             IOException,
                             URISyntaxException

Get the stats and external child IDs

Overrides:

getActionData in class JavaActionExecutor

Parameters:

actionFs - the FileSystem object

runningJob - the runningJob

action - the Workflow action

context - executor context

Throws:

HadoopAccessorException

org.jdom.JDOMException

IOException

URISyntaxException

getCaptureOutput

protected boolean getCaptureOutput(org.apache.oozie.client.WorkflowAction action)
                            throws org.jdom.JDOMException

Overrides:

getCaptureOutput in class JavaActionExecutor

Throws:

org.jdom.JDOMException

getDefaultShareLibName

protected String getDefaultShareLibName(org.jdom.Element actionXml)

Return the sharelib name for the action.

Overrides:

getDefaultShareLibName in class JavaActionExecutor

Parameters:

actionXml -

Returns:

returns sqoop.
