Github user HeartSaVioR commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/575#issuecomment-167734870 @Leemoonsoo I think https://github.com/apache/incubator-zeppelin/pull/576#issuecomment-167691292 would work, so if you don't mind adding "ping" to thrift procedure list and calling it, we can realize your origin intention.
