[SPARK-11000][YARN]Bug fix: Derby have booted the database twice in yarn
security mode.
[obtainTokenForHiveMetastore](https://github.com/apache/spark/blob/master/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala#L1267)
in yarn.Client.scala will init the `Hive`.
It will create a connect to the database and the meta store client in
`HiveContext` will also create a connect to the database. If use the derby by
default, it will go wrong.
So I specilized the configuration of the `javax.jdo.option.ConnectionURL`
in the `obtainTokenForHiveMetastore` to avoid this issue.
