   I had merged this pr and tested it on our test env.
   
   It seems that `process.destroyForcibly()` does not work.
   
   
   I have to found another temporary workaround.
   
   ```
     protected val KYUUBI_PROC_UNIQUE_ID: String = "kyuubi.proc.uniqueId"
   
     protected lazy val procUniqueId = UUID.randomUUID().toString
   
     protected def procConf(): Map[String, String] = Map(KYUUBI_PROC_UNIQUE_ID -> procUniqueId)
   ```
   
   ```
       var allConf = conf.getAll ++ procConf()
   ```
   
   
   ```
     protected def killProcessByUniqueId(): Unit = {
       val psEf = Runtime.getRuntime.exec("ps -ef")
       val input = new BufferedReader(new InputStreamReader(psEf.getInputStream))
       val regex = s"$KYUUBI_PROC_UNIQUE_ID=$procUniqueId".r
       var psInfo = input.readLine()
       var found = false
       while (!found && psInfo != null) {
         regex findFirstIn (psInfo) match {
           case Some(_) =>
             found = true
             psInfo.trim.split("\\s+").drop(1).headOption.foreach { psId =>
               Runtime.getRuntime.exec(s"kill -9 $psId")
             }
           case None =>
         }
         psInfo = input.readLine()
       }
     }
   
   ```
