Amir Youssefi commented on HADOOP-3315:
---------------------------------------

+1 on Util.java break-up. 

Initially, we had parts scattered in separate files,  then refactored those and 
put relevant parts into TFile, BCFile  and ones which didn't fit well went to 
Util.java file so we can deal with that  mix later. It's time to break up 
Util.java into a few files and hopefully get rid of some baggage and find a 
sweet spot. I suspect it may never be as sweet as we want ;) 

> New binary file format

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