guoxiaolongzte reopened SPARK-21325:
------------------------------------

1.My submit way:
spark-submit --class cn.gxl.TestSql -{color:red}-jars hdfs://nameservice:/gxl/spark-core_2.11-2.3.0-SNAPSHOT.jar,hdfs://nameservice:/gxl/zookeeper-3.4.6.jar --files hdfs://nameservice:/gxl/value1.txt,hdfs://nameservice:/gxl/value2.txt {color} hdfs://nameservice:/gxl/spark_2.0.2_project.jar

2.spark-submit  description：
  --jars JARS          {color:red}Comma-separated list of local jars{color} to include on the driver and executor classpaths.

  --files FILES         {color:red}Comma-separated list of files{color} to be placed in the working directory of each executor. File paths of these files in executors can be accessed via SparkFiles.get(fileName).

3.Problem Description：
 jars and files Not only can be placed on local but also  can be placed on hdfs.

The description of '' - jars '', that can only be placed on local.This is wrong

The description of '--files' is not clear that can be placed locally or hdfs.This is blurry. Not conducive to the developer to understand and use.

So, this is an optimization feature that deserves to be modified.
