Exiting Spark-shell from the scala script
提问by Ujjwal SIddharth
I am using this command to run scala scripts.
我正在使用此命令来运行 Scala 脚本。
spark-shell -i test.scala
At the end of the execution of the script I still see spark-shell running.
在脚本执行结束时，我仍然看到 spark-shell 正在运行。
I have used ":q/:quit" in the test.scala script to try and exit but it's not working.
我在 test.scala 脚本中使用了 ":q/:quit" 来尝试退出，但它不起作用。

You need to add exit() at the end of your script to avoid stepping into scala REPL.
您需要在脚本末尾添加 exit() 以避免进入 scala REPL。
Helloworld.scala
helloworld.scala
print("Hello World");
print("Second Line");
print("Bye now");
exit()
Run above
在上面跑
spark-shell -i helloworld.scala
