2.測試類

package com.dtwave.megrez


import java.util.Base64

import com.alibaba.fastjson.{JSONArray, JSONObject}
import org.apache.spark.sql.CarbonSession._
import org.apache.spark.sql.{DataFrame, SparkSession}
import org.apache.spark.{SparkConf, SparkContext}

import scala.io.Source

object MegrezApp {

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

    val Array(taskType, param) = args
    
    val conf = new SparkConf()
    conf.setAppName("lcc")
    conf.setMaster("local")
    val sc = new SparkContext(conf)

    val storePath = "hdfs://co1:9000/Opt/CarbonStore"
    //  這裡我們已經獲取到SparkSession了，可以像平常一樣操作spark
    val spark:SparkSession = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession(storePath)
	
	}
