Description

As the trace file generated by Rumen TraceBuilder is skipping some of the info like job counters, task counters, etc. we need a way to access "other info available in history file which is not dumped to trace file". This is useful for components which want to parse history files and get info. These components can directly use/leverage "Rumen's parsing of history files across hadoop releases" and get history info in a consistent way for further analysis/processing.
