Spark Idea Maven 开发环境搭建
1、安装jdkjava
jdk版本最好是1.7以上，设置好环境变量，安装过程，略。web
2、安装Mavensql
我选择的Maven版本是3.3.3，安装过程，略。apache
编辑Maven安装目录conf/settings.xml文件，api
<!-- 修改Maven 库存放目录--> <localRepository>D:\maven-repository\repository</localRepository>
3、安装Ideaapp
安装过程，略。maven
4、建立Spark项目tcp
一、新建一个Spark项目，oop
二、选择Maven，从模板建立项目，测试
三、填写项目GroupId等，
四、选择本地安装的Maven和Maven配置文件。
五、next
六、建立完毕，查看新项目结构：
七、自动更新Maven pom文件
八、编译项目
若是出现这种错误，这个错误是因为Junit版本形成的，能够删掉Test，和pom.xml文件中Junit的相关依赖，
即删掉这两个Scala类：
和pom.xml文件中的Junit依赖：
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
九、刷新Maven依赖
十、引入Jdk和Scala开发库
十一、在pom.xml加入相关的依赖包，包括Hadoop、Spark等
<dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> <type>jar</type> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.1</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.9</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-client</artifactId> <version>2.7.1</version> </dependency> <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-common</artifactId> <version>2.7.1</version> </dependency> <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-hdfs</artifactId> <version>2.7.1</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-core_2.10</artifactId> <version>1.5.1</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-sql_2.10</artifactId> <version>1.5.1</version> </dependency>
而后刷新maven的依赖，
十二、新建一个Scala Object。
测试代码为：
def main(args: Array[String]) {
println("Hello World!")
val sparkConf = new SparkConf().setMaster("local").setAppName("test")
val sparkContext = new SparkContext(sparkConf)
}
执行，
若是报了如下错误，
java.lang.SecurityException: class "javax.servlet.FilterRegistration"'s signer information does not match signer information of other classes in the same package at java.lang.ClassLoader.checkCerts(ClassLoader.java:952) at java.lang.ClassLoader.preDefineClass(ClassLoader.java:666) at java.lang.ClassLoader.defineClass(ClassLoader.java:794) 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$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at org.spark-project.jetty.servlet.ServletContextHandler.<init>(ServletContextHandler.java:136) at org.spark-project.jetty.servlet.ServletContextHandler.<init>(ServletContextHandler.java:129) at org.spark-project.jetty.servlet.ServletContextHandler.<init>(ServletContextHandler.java:98) at org.apache.spark.ui.JettyUtils$.createServletHandler(JettyUtils.scala:110) at org.apache.spark.ui.JettyUtils$.createServletHandler(JettyUtils.scala:101) at org.apache.spark.ui.WebUI.attachPage(WebUI.scala:78) at org.apache.spark.ui.WebUI$$anonfun$attachTab$1.apply(WebUI.scala:62) at org.apache.spark.ui.WebUI$$anonfun$attachTab$1.apply(WebUI.scala:62) at scala.collection.mutable.ResizableArray$class.foreach(ResizableArray.scala:59) at scala.collection.mutable.ArrayBuffer.foreach(ArrayBuffer.scala:47) at org.apache.spark.ui.WebUI.attachTab(WebUI.scala:62) at org.apache.spark.ui.SparkUI.initialize(SparkUI.scala:61) at org.apache.spark.ui.SparkUI.<init>(SparkUI.scala:74) at org.apache.spark.ui.SparkUI$.create(SparkUI.scala:190) at org.apache.spark.ui.SparkUI$.createLiveUI(SparkUI.scala:141) at org.apache.spark.SparkContext.<init>(SparkContext.scala:466) at com.test.Test$.main(Test.scala:13) at com.test.Test.main(Test.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:144)
能够把servlet-api 2.5 jar删除便可：
最好的办法是删除pom.xml中相关的依赖，即
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-client</artifactId>
<version>2.7.1</version>
</dependency>
最后的pom.xml文件的依赖是
<dependencies>
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.7.1</version>
</dependency>
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-hdfs</artifactId>
<version>2.7.1</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.10</artifactId>
<version>1.5.1</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-sql_2.10</artifactId>
<version>1.5.1</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>

</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-streaming_2.10</artifactId>
<version>1.5.2</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-mllib_2.10</artifactId>
<version>1.5.2</version>
</dependency>
<dependency>
<groupId>com.databricks</groupId>
<artifactId>spark-avro_2.10</artifactId>
<version>2.0.1</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-streaming_2.10</artifactId>
<version>1.5.2</version>
</dependency>
</dependencies>
若是是报了这个错误，也没有什么问题，程序依旧能够执行，
java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries. at org.apache.hadoop.util.Shell.getQualifiedBinPath(Shell.java:356) at org.apache.hadoop.util.Shell.getWinUtilsPath(Shell.java:371) at org.apache.hadoop.util.Shell.<clinit>(Shell.java:364) at org.apache.hadoop.util.StringUtils.<clinit>(StringUtils.java:80) at org.apache.hadoop.security.SecurityUtil.getAuthenticationMethod(SecurityUtil.java:611) at org.apache.hadoop.security.UserGroupInformation.initialize(UserGroupInformation.java:272) at org.apache.hadoop.security.UserGroupInformation.ensureInitialized(UserGroupInformation.java:260) at org.apache.hadoop.security.UserGroupInformation.loginUserFromSubject(UserGroupInformation.java:790) at org.apache.hadoop.security.UserGroupInformation.getLoginUser(UserGroupInformation.java:760) at org.apache.hadoop.security.UserGroupInformation.getCurrentUser(UserGroupInformation.java:633) at org.apache.spark.util.Utils$$anonfun$getCurrentUserName$1.apply(Utils.scala:2084) at org.apache.spark.util.Utils$$anonfun$getCurrentUserName$1.apply(Utils.scala:2084) at scala.Option.getOrElse(Option.scala:120) at org.apache.spark.util.Utils$.getCurrentUserName(Utils.scala:2084) at org.apache.spark.SparkContext.<init>(SparkContext.scala:311) at com.test.Test$.main(Test.scala:13) at com.test.Test.main(Test.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:144)
最后看到的正常输出：

至此，开发环境搭建完毕。
5、打jar包
一、新建一个Scala Object
代码是：
package com.test
import org.apache.spark.{SparkConf, SparkContext}
/**
* Created by pc on 2016/9/20.
*/
object WorldCount {
def main(args: Array[String]) {
val dataFile = args(0)
val output = args(1)
val sparkConf = new SparkConf().setAppName("WorldCount")
val sparkContext = new SparkContext(sparkConf)
val lines = sparkContext.textFile(dataFile)
val counts = lines.flatMap(_.split(",")).map(s => (s,1)).reduceByKey((a,b) => a+b)
counts.saveAsTextFile(output)
sparkContext.stop()
}
}
二、 File -》Project Structure
三、点击ok
能够设置jar包输出目录：
四、build Artifact
五、运行：
把测试文件放到HDFS的/test/ 目录下，提交：
spark-submit --class com.test.WorldCount --master spark://192.168.18.151:7077 sparktest.jar /test/data.txt /test/test-01
六、若是出现如下错误

就使用WinRAR打开jar包， 删除META-INF目录下的除了mainfest.mf，.rsa及maven目录之外的其余全部文件
