连接到Hive时Kinit与Spark

问题描述

有人可以让我知道如何在spark程序中执行kinit吗？我可以连接到配置单元？

更新：我的Spark与Hadoop位于不同的群集中

解决方案

 import java.lang.ProcessBuilder 
 import java.io.PrintWriter 
 
 //重置您的Kerberos登录
 val p1 = Runtime.getRuntime。 exec（kdestroy）
 p1.waitFor 
 //执行kinit，
 val p = Runtime.getRuntime.exec（kinit）
 val stdin = p.getOutputStream 
 val pw = new PrintWriter（stdin）
 // val pwd = get_password（）// get_password（）是一个函数，用于从文件或任何地方获取密码
 pw.println（pwd ）/ /你可以把你的密码放在这里，但普通的文本密码通常都会丢失ned upon 
 pw.close 
 p.waitFor 
  

I am trying to connect to Hive(hadoop cluster has kerberos authentication) from Spark which is Standalone.

Can someone let me know how to do kinit in spark program i could connect to hive?

UPDATE:My Spark is on different cluster from Hadoop

解决方案

Assuming you have a spark-shell open and you don't want to exit, and then re-kinit you could do something like this:

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
