ZEPPELIN-1242. Should set property SPARK_YARN_MODE and do login beforâ¦
### 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_bcb83nzzooedsbl...@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.
