What is this PR for?

We run zeppelin on spark when spark authentication is turned on, but got the following exception

The root cause is that we didn't set property SPARK_YARN_MODE just like spark-shell did.

The following code in Main.scala is what we miss in zeppelin spark interpreter. https://github.com/apache/spark/blob/branch-1.6/repl/scala-2.11/src/main/scala/org/apache/spark/repl/Main.scala

  def main(args: Array[String]) {
    if (getMaster == "yarn-client") System.setProperty("SPARK_YARN_MODE", "true")

Besides that, we need to do login before creating any spark stuff, otherwise will hit the classnotfound issue http://mail-archives.apache.org/mod_mbox/zeppelin-users/201606.mbox/%3CCAH-=KK2SzsXX5zvfnuoLbB1753Tm196_bcB83NzzooedSbLpRQ@mail.gmail.com%3E. The cause is that SecurityManager will add secretkey to credential, so before that we should do login, otherwise Executor can not connect to HttpFileServer on driver correctly due to the missing of secretkey.

LGTM. Re-trigger CI.

Merging this if no more discussion. CI fails looks unrelated.
