Hong Tang commented on HADOOP-3315:
-----------------------------------
@Stack,
Some work has been done based on comments we receive after our initial patch
release, major feature additions include:
- More efficient random access implementation. [Reader interface change]
- Customized comparator (support java class comparators).
- Added an ObjectFile layer on top of TFile, with corresponding InputFormat and
outputFormat.
I think it may be a good idea for us to upload another patch and collect
feedback. However, I have very limited time working on TFile now so I may not
be able to answer questions and address issues promptly.

> SequenceFile's block compression format is too complex and requires 4 codecs
