+1 for simplifying Kudu updates. I am also still on Ubuntu 14.04, but I am all for simplifying Kudu integration: I agree with Thomas that Kudu snapshots should be grouped with the other CDH components. Given that Ubuntu 14.04 will be EOL'd next spring, upgrading the development OS is a reasonably small price to pay -- especially that it will soon become necessary anyway.
