Edward Capriolo commented on HIVE-3585:
---------------------------------------

On one end when I look at hadoop core there is ALOT of stuff not really core to 
anything. A good example is DBInputFormat.

In Hive's case we do have quite a big code base, and at some point we may have 
so many UDF's and InputFormat's that we should draw a line on critical/vs 
extra. But we are not there yet. If it is just another serde+inputformat I am 
100% +1. 

Having hive avro gave us a big boost in project exposure and will help keep the 
ball rolling. Not everyone uses avro I/WE don't. But I really hate when I read 
a wiki with something to the effect of "Hive doesn't support X" when it 
actually does and X is just something easy waiting in the patch queue. Bring it 
on!
