@Leemoonsoo @bzz @felixcheung Finally I got the livy integration test
passed (failed test is flaky test, not related to this PR). I have to run livy
integration test separately. Because the travis docker container has 3 gb
memory limitation, the maven build process will be killed if I put livy
integration test with others. Several other livy PR depends on this PR, so I
hope get this PR merge first and plan to do the improvement of `.travis.yml` in
a following PR.
