@iijima-satoshi Could you try build zeppelin with the default hadoop
version (2.7) and run against hadoop 2.8 ? Because the goal of zeppelin is one
build instance of zeppelin to work with multiple hadoop & spark versions. And I
guess most likely it would work with hadoop 2.8 even you build it with hadoop
2.7---
