Abstract Value Members

  1. abstract def isValidJob(job: SparkJobBase): Boolean

    Permalink

    Returns true if the job is valid for this context.

    Returns true if the job is valid for this context. At the minimum this should check for if the job can actually take a context of this type; for example, a SQLContext should only accept jobs that take a SQLContext. The recommendation is to define a trait for each type of context job; the standard DefaultSparkContextFactory checks to see if the job is of type SparkJob.

  2. abstract def sparkContext: SparkContext

    The underlying SparkContext

  3. abstract def stop(): Unit

    Responsible for performing any cleanup, including calling the underlying context's stop method.
