You would either need to feed `spark-shell` a file containing the commands you want it to run (if it supports that) or make use of input redirection. spark-shell << EOF val sqlContext = new org.apache.spark.sql.SQLContext(sc) val df = sqlcontext.read.json("/file/path") EOF

MapReduce和Spark的区别是什么？
整个算法的瓶颈是不必要的数据读写，而Spark 主要改进的就是这一点。具体地，Spark 延续了MapReduce 的设计思路：对数据的计算也分为Map 和Reduce 两类。但不同的是，一个Spark 任务并不止包含一个Map 和一个Reduce，而是由一系列的Map、Reduce构成。 虽然Spark 的改进看似很小，但实验结果显示，它的算法性能相比MapReduce 提高了10～100 倍。 zhihu
