Bikas Saha commented on TEZ-2634:
---------------------------------

Many existing users may or may not be able to use new bits and releases. So 
being able to parse their job data via existing simple history logging would be 
great short term. So if the data is present (e.g. simple history logging + 
maybe dot file) then having that would be use for the analysers. If that is 
what this patch does then IMO we should take it while we wait for TEZ-2638 to 
be fully sorted out.

> Provide SimpleHistoryParser to parse SimpleHistoryLog and normalize to 
> in-memory datamodel provided in tez-history
