Profile的选择：
1. hadoop-2.4和YARN勾选，复选框中显示黑色的对号
2. hbase-hadoop1,maven-3,scala-2.10默认选择，复选框中显示灰的对号
问题：
1. PermGen内存
[ERROR] PermGen space -> [Help 1] java.lang.OutOfMemoryError: PermGen space at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) at java.net.URLClassLoader.access$100(URLClassLoader.java:71) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at scala.tools.nsc.Global.formatExplain(Global.scala:1140) at scala.tools.nsc.Global.supplementErrorMessage(Global.scala:1157) at scala.tools.nsc.Global$Run.compileUnits(Global.scala:1565) at scala.tools.nsc.Global$Run.compileSources(Global.scala:1553) at scala.tools.nsc.Global$Run.compile(Global.scala:1662)
Maven显示内存的使用情况Final Memory: 39M/827M，表示PermGen space为39M？
解决办法：https://cwiki.apache.org/confluence/display/MAVEN/OutOfMemoryError
在/etc/profile中添加如下Maven的内存设置（本机物理内存2G）
export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=512m"
这种做法适用于使用mvn在shell终端进行构建，如果在Intellij Idea中构建报这个错，则需要打开Idea的Maven配置窗口，在
Maven
Runner的VM OPTS中输入如下参数：
-Xmx1024m -XX:MaxPermSize=512m
2. Maven编译两个小时多之后，报编译错误，CodeGenerator.scala报很多错误.不过系统仍然可以编译

3.EventBatch.scala找不到
编译两个多小时，这个文件依然不存在，
j
4。经过4个小时的构建，终于编完了。。。竟然编译成功了，但是EventBatch依然不存在(所以，FlumeBatchFetcher.scala报错EventBatch和SparkFlumeProtocol不存在)和CodeGenerator.scala中依然无数的第二步的错

5.既然编译成功了，那就运行LocalPi.scala，触发Intellj Idea Make整个项目，又是一顿等待(这种情况产生的原因是什么？为什么不能只编译一个文件），make的结果是
Compilation completed with 44 errors and 37 warnings in 15 min 23 sec
查看出错信息，基本都是Spark SQL的catalyst相关的报错：
