Subject [GitHub] spark pull request: [SPARK-11201] [YARN] Make sure SPARK_YARN_MODE...

GitHub user harishreedharan opened a pull request:

    https://github.com/apache/spark/pull/9174

    [SPARK-11201] [YARN] Make sure SPARK_YARN_MODE is set before SparkHad…

    …oopUtil.get is called.
    
    If `StreamingContext.getOrCreate` is used in `yarn-client` mode, a `ClassCastException`
gets thrown when `Client.scala` is initialized and `YarnSparkHadoopUtil.get` is called. This
fails because the `SparkHadoopUtil.get` method is called in the `getOrCreate` method default
argument, before SPARK_YARN_MODE is set.
