The test +launches SimpleEntityWriter mappers or JobHistoryFileReplay mappers to write timeline +entities to the timeline server.

SimpleEntityWriter mapper + Each mapper writes a user-specified number of timeline entities + with a user-specified size to the timeline server. + + 2. JobHistoryFileReplay mapper + Each mapper replays jobhistory files under a specified directory + (both the jhist file and its corresponding conf.xml are required to + be present in order to be replayed. The number of mappers should be no more + than the number of jobhistory files). + Each mapper will get assigned some jobhistory files to replay. For each + job history file, a mapper will parse it to get jobinfo and then create + timeline entities.
