Scala本地连接带有kerberos的Hive

Scala本地连接带有kerberos的Hive,网上找了很多但是自己实际用起来还是连不上，所以贴上可用的版本。

XXX.keytab,krb5.conf,truststore这单个文件要在服务器上下载到本地，放在项目resources目录下的Kerberos目录下面。

代码中的confPath路径就是实际本地路径，例如项目resources目录下的Kerberos目录：

"C:\UseXXX\Project\MY_Projects\test3\src\main\resources\Kerberos\"

def initSpark() : SparkConf = {
    val isWin = System.getProperty("os.name").toLowerCase().startsWith("windows")
    println("current env isWin = "+isWin)
    val sparkConf = new SparkConf()
    if(isWin){
      val confPath = this.getClass.getClassLoader.getResource("Kerberos/").getPath
      // val confPath = "C:\Users\xXX\Project\MY_Projects\test3\src\main\resources\Kerberos\"
      println("confPath: "+confPath)
      val conf = new Configuration
      System.setProperty("java.security.krb5.conf", confPath + "krb5.conf")
      System.setProperty("javax.net.ssl.trustStore", confPath + "truststore")
      System.setProperty("javax.net.ssl.trustStorePassword", "changeit")
      System.setProperty("javax.security.auth.useSubjectCredsOnly", "false")
      System.setProperty("sun.security.krb5.debug", "true")
     // conf.set("hadoop.security.authentication", "Kerberos")
      UserGroupInformation.setConfiguration(conf)
      UserGroupInformation.loginUserFromKeytab("XXX@XXX.NET", confPath + "XXX.keytab")
      sparkConf.set("spark.yarn.keytab", confPath + "XXX.keytab").set("spark.yarn.principal", "XXX@XXX.NET")
      System.out.println(UserGroupInformation.getCurrentUser)
    }
    return sparkConf    
  }

调用代码如下：

def main(args: Array[String]): Unit = {  

  //设置日志输出级别
  Logger.getLogger("org").setLevel(Level.WARN)
  val sparkSession = SparkSession.builder().appName("test1").master("local[*]").config(InitSpark().initSpark()).enableHiveSupport.getOrCreate
  sparkSession.sql("select * from table ").show()
  sparkSession.sparkContext.stop()

}
