-----------------------------------------
I did two test builds of curator with guava set to 11.0.2. Curator 2.4.1
builds; Curator 2.6.0 fails in {{curator-x-discovery-server}}:

This implies that part of curator is not compatible with guava 11, though it is
not a core module.
As 2.4.1 builds without problems, I think the patch should still go in
> Hadoop now has transient dependency on Guava 16

> Key: HADOOP-11102
> URL: https://issues.apache.org/jira/browse/HADOOP-11102
> Project: Hadoop Common
> Issue Type: Bug
> Components: build
> Affects Versions: 2.6.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Attachments: HADOOP-11102-001.patch, HADOOP-11102-002.patch

>
> HADOOP-10868 includes apache curator 2.6.0
> This depends on Guava 16.01
> It's not being picked up, as Hadoop is forcing in 11.0.2 -but this means:
> there is now a risk that curator depends on methods and classes that are not
> in the Hadoop version
