Hong Tang commented on HADOOP-3315:
-----------------------------------
bq. This new Scanner API is still Comparator-free. It's easy to layer
lexicographic-by-byte on top of a Comparator-based API, but not vice versa.
We are working on that as a separate task. The complete task list is as follows:
* random access (which is what my early long comment is about)
* customized comparator on TFile.
* supporting objects and input/output format for MapReduce
* extensibility.
Expect more comments addressing these issues soon.

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