In FusionInsight HD, which method of the OozieClient class will be called by the JAVA API of the Oozie client when running tasks?

Options

• Asuspend
• BgetJobInfo
• Csubmit
• Drun

• A

• B
  15% (4)
• C
  8% (2)
• D
  73% (19)

Explanation

run() is correct because the Oozie Java API's OozieClient.run() method both submits and immediately starts execution of a workflow job in a single call - which is the standard way to "run a task" programmatically in FusionInsight HD.

• A (suspend) - suspend() pauses a job that is already running; it has nothing to do with initiating execution.
• B (getJobInfo) - getJobInfo() is a read-only query that retrieves status/metadata about an existing job; it performs no execution.
• C (submit) - submit() only registers the job with the Oozie server and returns a job ID without starting it; a separate start() call would then be needed to begin execution.

Memory tip: Think of run() as the "one-shot" method - it collapses submit + start into a single step, which is exactly what you'd want when the goal is simply to run a task right away.
