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
getStageInfocould potentially returnNonefor 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
