Guava did make the lives of Hadoop development easier in many cases -- What I've been consistently hearing is that the version of Guava used is Hadoop is so old that it starts to hurt the application developers.
I appreciate the value of Guava -- things like CacheMap are fairly difficult to implement efficiently and correctly. I think that creating separate client libraries for Hadoop can largely alleviate the problem -- obviously these libraries cannot use Guava, but it allows us to use Guava's help on the server side. For example, HDFS-6200 is one of the initiatives. Just my two cents.
