Proposed Solution: 

A lightweight layer/extension on top of TFile called ObjectFile. 

Rationale:
Two options were considered: 

A) ObjectFile as described above.
B) Having Object Support only in Input/Output Format (JIRA:  HADOOP-4322)

Option A can be used by map-reduce jobs as well as others. Option A has more direct relation with SequenceFile.
