One CI failure https://travis-ci.org/herval/zeppelin/jobs/283036367 is
license check and looks like
`zeppelin-interpreter/src/main/java/org/apache/zeppelin/user/Encryptor.java`
misses apache license header in the beginning of the file.
@herval do you mind add license header to this file?
Other CI failure looks unrelated. so looks good to me except for this
license header.---
