安装开发环境的 Hadoop

1) 解压缩，修改配置文件：

1.1) hadoop-env.sh

export JAVA_HOME=/usr/local/jvm/jdk

1.2) core-site.xml

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://t420i:8020</value>
    </property>
    <property>
        <name>hadoop.tmp.dir</name>
        <value>/works/datas/hadoop/tmp</value>
    </property>
</configuration>

1.3) hdfs-site.xml

<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
</configuration>

2.) 执行命令命令行执行格式化 HDFS

YARN

2.) 编辑 site 文件

2.1) mapred-site.xml

<configuration>
    <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
    </property>
</configuration>

2.2) yarn-site.xml

<configuration>

<!-- Site specific YARN configuration properties -->

    <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
    </property>
</configuration>

2.3) 启动 YARN

$HADOOP_HOME/sbin/start-yarn.sh

Hadoop 的 Web 界面

hdfs：http://t420i:50070/

yarn：http://t420i:8088/cluster

Spark 编译

1.) 下载 src，解压

前置要求：

1.1）：maven 3.5； jdk1.8

2.2）：export MAVEN_OPTS=”-Xmx2g -XX:ReservedCodeCacheSize=512m”

mvn 编译命令：

$ mvn -Pyarn -Phadoop-2.4 -Dhadoop.version=2.4.0 -DskipTests clean package

$ ./dev/make-distribution.sh \
--name 2.6.0-cdh5.16.2 --tgz \
-Pyarn -Phadoop-2.6 \
-Phive -Phive-thriftserver \
-Pscala-2.11 \
-Dhadoop.version=2.6.0

环境变量

export JAVA_HOME='/usr/local/jvm/jdk'
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export M2_HOME='/usr/local/jvm/maven'
export SCALA_HOME='/usr/local/jvm/scala'

# setup hadoop env
export HADOOP_HOME='/works/apps/hadoop'
export HADOOP_PREFIX=$HADOOP_HOME
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME
export HADOOP_INSTALL=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME

Spark 部署

(local 模式)

啥都不用改, 解压到指定位置. 即可.

把 spark 加到系统环境变量中.

$ spark-shell --master local[2]

(standalone 模式)

Spark standalone 模式的架构和 Hadoop HDFS/YARN 类似, 即 1 个 Master 带多个 Worker.

首先调整配置文件

cd conf/
cp spark-env.sh.template spark-env.sh


# Options for the daemons used in the standalone deploy mode
# - SPARK_MASTER_HOST, to bind the master to a different IP address or hostname
# - SPARK_MASTER_PORT / SPARK_MASTER_WEBUI_PORT, to use non-default ports for the master
# - SPARK_MASTER_OPTS, to set config properties only for the master (e.g. "-Dx=y")
# - SPARK_WORKER_CORES, to set the number of cores to use on this machine
# - SPARK_WORKER_MEMORY, to set how much total memory workers have to give executors (e.g. 1000m, 2g)
# - SPARK_WORKER_PORT / SPARK_WORKER_WEBUI_PORT, to use non-default ports for the worker
# - SPARK_WORKER_DIR, to set the working directory of worker processes
# - SPARK_WORKER_OPTS, to set config properties only for the worker (e.g. "-Dx=y")
# - SPARK_DAEMON_MEMORY, to allocate to the master, worker and history server themselves (default: 1g).
# - SPARK_HISTORY_OPTS, to set config properties only for the history server (e.g. "-Dx=y")
# - SPARK_SHUFFLE_OPTS, to set config properties only for the external shuffle service (e.g. "-Dx=y")
# - SPARK_DAEMON_JAVA_OPTS, to set config properties for all daemons (e.g. "-Dx=y")
# - SPARK_DAEMON_CLASSPATH, to set the classpath for all daemons
# - SPARK_PUBLIC_DNS, to set the public dns name of the master or workers
SPARK_MASTER_HOST=192.168.56.123
SPARK_WORKER_CORES=2
SPARK_WORKER_MEMORY=2g
SPARK_WORKER_INSTANCES=1

sbin/start-all.sh
bin/spark-shell --master spark://192.168.56.123:7077

一个 WordCount 的示例:

val file = spark.sparkContext.textFile("file:///home/chengchao/data/wc.txt")
val wordCounts = file.flatMap(line => line.split(",")).
  map(word => (word, 1)).
  reduceByKey(_ + _)
wordCounts.collect

提交作业

bin/spark-submit \
  --class <main-class> \
  --master <master-url> \
  --deploy-mode <deploy-mode> \
  --conf <key=value> \
  ... # other options
  <application-jar> \
  [application-arguments]

 spark-submit --class cn.chengchaos.spark.sql.bba.BbaDemo1App1 \
   --master yarn \
   my-spark-demo-jar-with-dependencies.jar
 spark-submit --class cn.chengchaos.spark.sql.bba.BbaDemo1App1 \
   --master local[2] \
