new SparkStatusTracker()
Low-level status reporting APIs for monitoring job and stage progress.
These APIs intentionally provide very weak consistency semantics; consumers of these APIs should
be prepared to handle empty / missing information. For example, a job's stage ids may be known
but the status API may not have any information about the details of those stages, so
`getStageInfo` could potentially return `None` for a valid stage id.
To limit memory usage, these APIs only provide information on recent jobs / stages. These APIs
will provide information for the last `spark.ui.retainedStages` stages and
`spark.ui.retainedJobs` jobs.
NOTE: this class's constructor should be considered private and may be subject to change.
