i think it's not the drill's version problem .because my own vm did have the same problem .and use the
1.8 drill.

@AisTop

Make sure you are running with java 1.8. It looks like class version not match.

Also, I recently push a new commit ( shunfei/drill@3018217 ) to indexr-drill-1.8.0 branch, in https://github.com/shunfei/drill project. If you still have problem, try pull this branch to latest version and recompile the drill-indexr-storage-1.8.0.jar.
