Description

This is pretty minor, more due diligence than any binary compatibility.

1. the hadoop-2.7 profile declares the curator version to be 2.6.0
2. the actual hadoop-2.7.1 dependency is of curator 2.7.1; this came from HADOOP-11492

For consistency, the profile can/should be changed. However, note that as well as some incompatibilities defined in HADOOP-11492; the version of Guava that curator asserts a need for is 15.x. HADOOP-11612 showed what needed to be done to address compatibility problems there; one of the Curator classes had to be forked to make compatible with guava 11+
