> We should remove Guava and shade the other depdendencies in the HTrace subprojects.
> * protobuf: *must* be shaded.  Hadoop and HBase pull in their own version-- there's no guarantee that it will be the same as ours.  And protobuf broke cross-version compatibility in the past (i.e. during the 2.4 -> 2.5 transition)
> * Apache Thrift: should be shaded.  We don't want to fight with the host application about versions of Thrift.
> * Guava: should be removed.  We hardly use it at all, and its cross-version compatibility policy is a mess.
