spark 1.3.0下的问题

1.在spark SQL的一个test中
无论是registerAsTable还是registerTempTable 都会有问题，经过查找各种资料，采用如下的方式：

val sqlCon=new org.apache.spark.sql.SQLContext(sc)
import sqlContext.
val data=sc.textFile("hdfs://spark-master.dragon.org:8020/user/a.csv")
case class Person(cname:String,age:Int )
val people=data.map(.split(",")).map(p=>Person(p(0),p(1).toInt))
people.toDF.registerTempTable("people")
sql("select * from people").collect
2.有一个问题待解决下边的程序中，如果我在ide里边打包，然后用spark-submit运行，会运行的很正确，如果放在ide里边直接运行，会报错，但是改成local模式怎没有问题报错内容在最下边展示着，这个问题还一直没有解决，待续

package com.san.spark.basic

import org.apache.spark.{SparkContext, SparkConf}

/**

• Created by hadoop on 3/23/16.
  */
  object aaa {
  def main(args: Array[String]) {
  val logFile = "hdfs://spark-master:8020/user/sparkS/a.csv" // Should be some file on your system
  val conf = new SparkConf().setAppName("aa") //
  .setMaster("spark://spark-master:7077")
  //.setJars(List("/opt/data01/myTes/aaa.jar"))
  // .setMaster("local")
  val sc = new SparkContext(conf)
  //sc.addJar("/opt/data01/myTes/aaa.jar")
  val logData = sc.textFile(logFile, 2).cache()
  val numAs = logData.filter(line => line.contains("a")).count()
  val numBs = logData.filter(line => line.contains("b")).count()
  println("Lines with a: %s, Lines with b: %s".format(numAs, numBs))
  sc.stop()
  }
  }

我运行的程序很简单：
package com.github

import java.util.Random

import org.apache.spark.{SparkConf, SparkContext}

/**

• Created by hadoop on 3/27/16.
  */
  object GroupByTest {
  def main(args: Array[String]) {
  val sparkConf = new SparkConf().setAppName("GroupBy Test")
  var numMappers = if (args.length > 0) args(0).toInt else 2
  var numKVPairs = if (args.length > 1) args(1).toInt else 1000
  var valSize = if (args.length > 2) args(2).toInt else 1000
  var numReducers = if (args.length > 3) args(3).toInt else numMappers

  val sc = new SparkContext(sparkConf)

  val pairs1 = sc.parallelize(0 until numMappers, numMappers).flatMap { p =>
  val ranGen = new Random
  var arr1 = new Array(Int, Array[Byte])
  for (i <- 0 until numKVPairs) {
  val byteArr = new ArrayByte
  ranGen.nextBytes(byteArr)
  arr1(i) = (ranGen.nextInt(Int.MaxValue), byteArr)
  }
  arr1
  }.cache()
  // Enforce that everything has been calculated and in cache
  pairs1.count()

  println(pairs1.groupByKey(numReducers).count())

  sc.stop()
  }
  }
  原因很简单，我没有设置VM Options ，因此我只需点击 run---run configurations---配置参数即可，截图如下：
  即可

4.在终端下运行我的第一个spark streaming的时候，提示：

原因是我的9999端口没有打开，
查看端口：netstat -an | grep 9999
打开端口：nc -lp 9999 &
