| 为了在IDEA中编写scala，今天安装配置学习了IDEA集成开发环境。IDEA确实很优秀，学会之后，用起来很顺手。关于如何搭建scala和IDEA开发环境，请看文末的参考资料。
用Scala和Java实现WordCount，其中Java实现的JavaWordCount是spark自带的例子（$SPARK_HOME/examples/src/main/java/org/apache/spark/examples/JavaWordCount.java）
1.环境
OS:Red Hat Enterprise Linux Server
release 6.4 (Santiago)
Hadoop:Hadoop 2.4.1
JDK:1.7.0_60
Spark:1.1.0
Scala:2.11.2
集成开发环境：IntelliJ IDEA 13.1.3
注意：需要在客户端windows环境下安装IDEA、Scala、JDK，并且为IDEA下载scala插件。
2.Scala实现单词计数
package com.hq

4 * User: hadoop
5 * Date: 2014/10/10 0010
6 * Time: 18:59
7 */
8 import org.apache.spark.SparkConf
9 import org.apache.spark.SparkContext
10 import org.apache.spark.SparkContext._
11
12 /**
13 * 统计字符出现次数
14 */
15 object WordCount {
16 def main(args: Array[String]) {
17 if (args.length < 1) {
18 System.err.println("Usage: <file>")
19 System.exit(1)
20 }
21
22 val conf = new SparkConf()
23 val sc = new SparkContext(conf)
24 val line = sc.textFile(args(0))
25
26 line.flatMap(_.split(" ")).map((_, 1)).reduceByKey(_+_).collect().foreach(println)
27
28 sc.stop()
29 }
30 } |
3.Java实现单词计数

9 import org.apache.spark.SparkConf;
10 import org.apache.spark.api.java.JavaPairRDD;
11 import org.apache.spark.api.java.JavaRDD;
12 import org.apache.spark.api.java.JavaSparkContext;
13 import org.apache.spark.api.java.function.FlatMapFunction;
14 import org.apache.spark.api.java.function.Function2;
15 import org.apache.spark.api.java.function.PairFunction;
16 import scala.Tuple2;
17
18 import java.util.Arrays;
19 import java.util.List;
20 import java.util.regex.Pattern;
21
22 public final class JavaWordCount {
23 private static final Pattern SPACE = Pattern.compile(" ");
24
25 public static void main(String[] args) throws Exception {
26
27 if (args.length < 1) {
28 System.err.println("Usage: JavaWordCount <file>");
29 System.exit(1);
30 }
31
32 SparkConf sparkConf = new SparkConf().setAppName("JavaWordCount");
33 JavaSparkContext ctx = new JavaSparkContext(sparkConf);
34 JavaRDD<String> lines = ctx.textFile(args[0], 1);
35
36 JavaRDD<String> words = lines.flatMap(new FlatMapFunction<String, String>() {
37 @Override
38 public Iterable<String> call(String s) {
39 return Arrays.asList(SPACE.split(s));
40 }
41 });
42
43 JavaPairRDD<String, Integer> ones = words.mapToPair(new PairFunction<String, String, Integer>() {
44 @Override
45 public Tuple2<String, Integer> call(String s) {
46 return new Tuple2<String, Integer>(s, 1);
47 }
48 });
49
50 JavaPairRDD<String, Integer> counts = ones.reduceByKey(new Function2<Integer, Integer, Integer>() {
51 @Override
52 public Integer call(Integer i1, Integer i2) {
53 return i1 + i2;
54 }
55 });
56
57 List<Tuple2<String, Integer>> output = counts.collect();
58 for (Tuple2<?, ?> tuple : output) {
59 System.out.println(tuple._1() + ": " + tuple._2());
60 }
61 ctx.stop();
62 }
63 } |
4.IDEA打包和运行
4.1 IDEA的工程结构
在IDEA中建立Scala工程，并导入spark api编程jar包（spark-assembly-1.1.0-hadoop2.4.0.jar：$SPARK_HOME/lib/里面）
4.2 打成jar包
File ---> Project Structure
配置完成后，在菜单栏中选择Build->Build Artifacts...，然后使用Build等命令打包。打包完成后会在状态栏中显示“Compilation
completed successfully...”的信息，去jar包输出路径下查看jar包，如下所示。
ScalaTest1848.jar就是我们编程所产生的jar包，里面包含了三个类HelloWord、WordCount、JavaWordCount。
可以用这个jar包在spark集群里面运行java或者scala的单词计数程序。
4.3 以Spark集群standalone方式运行单词计数
上传jar包到服务器，并放置在/home/ebupt/test/WordCount.jar路径下。
上传一个text文本文件到HDFS作为单词计数的输入文件：hdfs://eb170:8020/user/ebupt/text
内容如下
1 import org apache spark api java JavaPairRDD
2 import org apache spark api java JavaRDD
3 import org apache spark api java JavaSparkContext
4 import org apache spark api java function FlatMapFunction
5 import org apache spark api java function Function
6 import org apache spark api java function Function2
7 import org apache spark api java function PairFunction
8 import scala Tuple2 |
用spark-submit命令提交任务运行，具体使用查看：spark-submit --help
1 [ebupt@eb174 bin]$ spark-submit --help
2 Spark assembly has been built with Hive, including Datanucleus jars on classpath
3 Usage: spark-submit [options] <app jar | python file> [app options]
4 Options:
5 --master MASTER_URL spark://host:port, mesos://host:port, yarn, or local.
6 --deploy-mode DEPLOY_MODE Whether to launch the driver program locally ("client") or
7 on one of the worker machines inside the cluster ("cluster")
8 (Default: client).
9 --class CLASS_NAME Your application's main class (for Java / Scala apps).
10 --name NAME A name of your application.
11 --jars JARS Comma-separated list of local jars to include on the driver
12 and executor classpaths.
13 --py-files PY_FILES Comma-separated list of .zip, .egg, or .py files to place
14 on the PYTHONPATH for Python apps.
15 --files FILES Comma-separated list of files to be placed in the working
16 directory of each executor.
17
18 --conf PROP=VALUE Arbitrary Spark configuration property.
19 --properties-file FILE Path to a file from which to load extra properties. If not
20 specified, this will look for conf/spark-defaults.conf.
21

23 --driver-java-options Extra Java options to pass to the driver.
24 --driver-library-path Extra library path entries to pass to the driver.
25 --driver-class-path Extra class path entries to pass to the driver. Note that
26 jars added with --jars are automatically included in the
27 classpath.
28
29 --executor-memory MEM Memory per executor (e.g. 1000M, 2G) (Default: 1G).
30
31 --help, -h Show this help message and exit
32 --verbose, -v Print additional debug output
33
34 Spark standalone with cluster deploy mode only:
35 --driver-cores NUM Cores for driver (Default: 1).
36 --supervise If given, restarts the driver on failure.
37
38 Spark standalone and Mesos only:
39 --total-executor-cores NUM Total cores for all executors.
40
41 YARN-only:
42 --executor-cores NUM Number of cores per executor (Default: 1).
43 --queue QUEUE_NAME The YARN queue to submit to (Default: "default").
44 --num-executors NUM Number of executors to launch (Default: 2).
45 --archives ARCHIVES Comma separated list of archives to be extracted into the
46 working directory of each executor. |
①提交scala实现的单词计数：
[ebupt@eb174 test]$ spark-submit --master spark://eb174:7077
--name WordCountByscala --class com.hq.WordCount --executor-memory
1G --total-executor-cores 2 ~/test/WordCount.jar hdfs://eb170:8020/user/ebupt/text
②提交java实现的单词计数：
[ebupt@eb174 test]$ spark-submit --master spark://eb174:7077
--name JavaWordCountByHQ --class com.hq.JavaWordCount
--executor-memory 1G --total-executor-cores 2 ~/test/WordCount.jar
hdfs://eb170:8020/user/ebupt/text
③2者运行结果类似，所以只写了一个：
