Hello,well.......What I ask may be a very simple question,but still trouble me......
Before I ask the question,I have read the http://spark.apache.org/contributing.html , And search for the mailing list,But still not sure^_^. The question is like that: In org.apache.spark.streaming.dstream of Spark 2.11 Scala Package,functions are as bellow: ``` override def slideDuration: Duration = { if (ssc == null) throw new Exception("ssc is null") if (ssc.graph.batchDuration == null) throw new Exception("batchDuration is null") ssc.graph.batchDuration } ``` But Whether use more specific Exception Reference will be better ? like this: ``` override def slideDuration: Duration = { import org.apache.spark.SparkException if (ssc == null) throw new SparkException("ssc is null") if (ssc.graph.batchDuration == null) throw new SparkException("batchDuration is null") ssc.graph.batchDuration } ``` But After all,the system will exit once the exception is throw,so it seems that just error information will be clear enough... But code change like this is someways like typo fix,and how much sense will it make to consumer conmitter's time to review it ?
