Date Wed, 27 Jan 2016 19:17:45 GMT
+1. (binding)

- Compat report looks good.
- Checked signatures, looks good
- Built from source, site, docs, rat, looks good
 -- ('mvn clean test site -DskipTests' initially failed; but mvn clean test
- Ran ITBLL, ITAcidGuarantees, and ITIngest on 5 node cdh 5.5.0 hadoop
cluster; they passed
