Steve Loughran commented on HADOOP-10101:
-----------------------------------------

[~ajs6f] [~bpodgursky] : you should know that even though Hadoop ships a 
woefully out of date Guava version, it does run against later ones, up to 18, 
AFAIK; every time they pull something we've had to jump though hoops 
(HADOOP-10961) to implicitly keep up. 

Shading is going to be the Java 8 solution, until java 9 gives us {{jlink}} and 
we can adopt it (how? when?); IMO we'll have to shade not just guava, but if we 
can include Avro, then, along with protobuf (done) we've got the 
high-brittleness and IPC-critical serialization libs sorted

As far as we are aware, there are no APIs marked as public which export guava 
classes. This is a good thing, and does at least give us some freedom.
