package jobserver
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.
The underlying SparkContext
Responsible for performing any cleanup, including calling the underlying context's stop method.
Represents a context based on SparkContext. Examples include: StreamingContext, SQLContext.
The Job Server can spin up not just a vanilla SparkContext, but anything that implements ContextLike.
