> SPARK-16757 sets the hadoop {{CallerContext}} when calling hadoop/hdfs apis to make spark applications more diagnosable in hadoop/hdfs logs. However, the {{CallerContext}} is only added since hadoop 2.8. So each time {{utils.CallerContext.setCurrentContext()}} is called (e.g when a task is created), a "java.lang.ClassNotFoundException: org.apache.hadoop.ipc.CallerContext"
>   error is logged.
> We should improve this so it's only logged once.
