Aaron, It's not CDH5 per se that is raising the risk profile but rather Cloudera's implementation of Map Reduce 1 with CDH5. They have custom libs built for hadoop-core, hadoop-minicluster, hadoop-client, and hadoop-test all versioned as 2.3.0-mr1-cdh5.0.2 as well as all the MR1 daemons (NN, TT, JT) using the hadoop2 filesystem.

The build run's against hadoop 2.2.0 and I have successfully run Blur on HDP 2.1 (based on hadoop 2.4.0). I don't mind running the tests and minicluster against CDH5 if this will help in your decision making process. https://builds.apache.org/job/Blur-master-jdk7-hadoop2/ Thanks!
