[SPARK-11201] [YARN] Make sure SPARK_YARN_MODE is set before SparkHadâ¦
â¦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.
