# vim /usr/local/hadoop/etc/hadoop/slaves
datanode1
datanode2
datanode3

------------------------------------------------------------------------------------------------------------------------------------------

9、Hadoop 简单测试
# cd /usr/local/hadoop


## 首次启动集群时,做如下操作【主名字节点上执行】
# hdfs namenode -format
# sbin/start-dfs.sh


## 检查进程是否正常启动
# jps

主名字节点:

wKioL1LaEMrjQacwAABONcvG8Dg225.jpg


备名字节点:

wKiom1LaEQuSjLGuAABH6tWl1S8405.jpg


数据节点:

## hdfs与mapreduce测试
# hdfs dfs -mkdir -p /user/rocketzhang
# hdfs dfs -put bin/hdfs.cmd /user/rocketzhang
# hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar wordcount /user/rocketzhang /user/out
# hdfs dfs -ls /user/out


## hdfs信息查看
# hdfs dfsadmin -report
# hdfs fsck / -files -blocks

========================================================================================
四、Spark 分布式集群配置【注:所有节点都做同样配置】
========================================================================================
1、Scala 安装
http://www.scala-lang.org/files/archive/scala-2.9.3.tgz

# tar xvzf scala-2.9.3.tgz -C /usr/local
# cd /usr/local
# ln -s scala-2.9.3 scala


# vim /etc/profile
export SCALA_HOME=/usr/local/scala
export PATH=$PATH:$SCALA_HOME/bin


# source /etc/profile

------------------------------------------------------------------------------------------------------------------------------------------

2、Spark 安装
http://d3kbcqa49mib13.cloudfront.net/spark-0.8.1-incubating-bin-hadoop2.tgz

# tar xvzf spark-0.8.1-incubating-bin-hadoop2.tgz -C /usr/local
# cd /usr/local
# ln -s spark-0.8.1-incubating-bin-hadoop2 spark


# vim /etc/profile
export SPARK_HOME=/usr/local/spark
export PATH=$PATH:$SPARK_HOME/bin


# source /etc/profile


# cd /usr/local/spark/conf
# mv spark-env.sh.template spark-env.sh

# vim spark-env.sh
export JAVA_HOME=/usr/local/jdk
export SCALA_HOME=/usr/local/scala
export HADOOP_HOME=/usr/local/hadoop


## worker节点的主机名列表
# vim slaves
datanode1
datanode2
datanode3


# mv log4j.properties.template log4j.properties

## 在Master节点上执行
# cd /usr/local/spark && .bin/start-all.sh


## 检查进程是否启动【在master节点上出现Master,在slave节点上出现Worker
# jps

Master节点:

wKioL1LaE7zwSI2KAABylj7nVfk839.jpg


Slave节点:

wKiom1LaFDnT4bAqAABuLr2Rlm8322.jpg

------------------------------------------------------------------------------------------------------------------------------------------

3、相关测试
## 监控页面URL
http://10.217.145.244:8080/

wKioL1LaFMXCcqgxAAQWNSUG3xU978.jpg


## 先切换到/usr/local/spark目录
(1)、本地模式
# ./run-example org.apache.spark.examples.SparkPi local


(2)、普通集群模式
# ./run-example org.apache.spark.examples.SparkPi spark://namenode1:7077
# ./run-example org.apache.spark.examples.SparkLR spark://namenode1:7077
# ./run-example org.apache.spark.examples.SparkKMeans spark://namenode1:7077 file:/usr/local/spark/kmeans_data.txt 2 1


(3)、结合HDFS的集群模式
# hadoop fs -put README.md .
# MASTER=spark://namenode1:7077 ./spark-shell
scala> val file = sc.textFile("hdfs://namenode1:9000/user/root/README.md")
scala> val count = file.flatMap(line => line.split(" ")).map(word => (word, 1)).reduceByKey(_+_)
scala> count.collect()
scala> :quit


(4)、基于YARN模式
# SPARK_JAR=./assembly/target/scala-2.9.3/spark-assembly_2.9.3-0.8.1-incubating-hadoop2.2.0.jar \
./spark-class org.apache.spark.deploy.yarn.Client \
--jar examples/target/scala-2.9.3/spark-examples_2.9.3-assembly-0.8.1-incubating.jar \
--class org.apache.spark.examples.SparkPi \
--args yarn-standalone \
--num-workers 3 \
--master-memory 4g \
--worker-memory 2g \
--worker-cores 1


执行结果:
/usr/local/hadoop/logs/userlogs/application_*/container*_000001/stdout


(5)、其他一些样例程序
examples/src/main/scala/org/apache/spark/examples/


(6)、问题定位【数据节点上的日志】
/data/hadoop/storage/tmp/nodemanager/logs


(7)、一些优化
# vim /usr/local/spark/conf/spark-env.sh
export SPARK_WORKER_MEMORY=16g  【根据内存大小进行实际配置】
......


(8)、最终的目录结构
