假设你有一个Spark壳打开，你不想退出，然后重新扭结，你可以这样做：

import java.lang.ProcessBuilder
import java.io.PrintWriter

//resets your kerberos login
val p1 = Runtime.getRuntime.exec("kdestroy")
p1.waitFor
//executes kinit, 
val p = Runtime.getRuntime.exec("kinit")
val stdin = p.getOutputStream
val pw =new PrintWriter(stdin)
//val pwd = get_password() //get_password() is a function to get your password from a file, or wherever
pw.println(pwd) // you could put your password here , but plain text passwords are generally frowned upon
pw.close
p.waitFor

您应该在初始化spark shell或提交spark应用程序（spark submit）之前运行kinit命令。另一个选项是使用keytab获取kerberos票证，然后像这样运行spark程序

bash -c "kinit -kt /path/to/key/mykey.keytab myuser@KERBEROS.SERVER.COM; spark-shell"

当做，
