<div class="block">Low-level status reporting APIs for monitoring job and stage progress.
<p>
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
<code>getStageInfo</code> could potentially return <code>None</code> for a valid stage id.
<p>
To limit memory usage, these APIs only provide information on recent jobs / stages. These APIs
will provide information for the last <code>spark.ui.retainedStages</code> stages and
<code>spark.ui.retainedJobs</code> jobs.

NOTE: this class's constructor should be considered private and may be subject to change.</div>
