1、scalaIDE 运行提示报错：Please use a larger heap size
2、修改jdk 使用内存 找到eclispe 中window->preferences->Java->Installed JRE ，点击右侧的Edit 按钮，在编辑界面中的 “Default VM Arguments ”选项中，填入如下值即可。
-Xms128m -Xmx512m
3、修改读入windows本地文件的路径
val conf = new SparkConf() //创建SparkConf对象 conf.setAppName("Wow,My First Spark App!") //设置应用程序的名称，在程序运行的监控界面可以看到名称 conf.setMaster("local") //此时，程序在本地运行，不需要安装Spark集群
val lines = sc.textFile("G://IMFBigDataSpark2016//Bigdata_Software//spark-1.6.0-bin-hadoop2.6//spark-1.6.0-bin-hadoop2.6//spark-1.6.0-bin-hadoop2.6//README.md", 1) //读取本地文件并设置为一个Partion
4、运行搞定！

5、hadoop 找不到的问题，将导入winutils.exe包来解决
16/01/14 11:58:26 WARN NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 16/01/14 11:58:26 ERROR Shell: Failed to locate the winutils binary in the hadoop binary path java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries.
