一、启动环境
启动脚本：bigdata-start.sh
#!/bin/bash echo -e " ========Start run zkServer======== " for nodeZk in node180,node181,node182;do ssh $nodeZk "zkServer.sh start;jps";done sleep 10 echo -e " ========Start run journalnode======== " hdfs --daemon start journalnode jps sleep 5 echo -e " ========Start run dfs======== " start-dfs.sh jps sleep 5 echo -e " ========Start run yarn======== " start-yarn.sh sleep 5 echo -e " ========Start run hbase======== " start-hbase.sh sleep 5 echo -e " ========Start run kafka======== " for nodeKa in node180,node181,node182;do ssh $nodeKa "kafka-server-start.sh /opt/module/kafka_2.12-2.0.1/config/server.properties &;jps";done sleep 15 echo -e " ========Start run spark======== " cd /opt/module/spark-3.0.0-hadoop3.2/sbin/ ./start-all.sh sleep 5 jps
二、测试准备
1、创建spark在HDFS集群中的输入路径
hdfs dfs -mkdir -p /spark/input
2、本地创建测试数据
3、上传HDFS集群中
hdfs dfs -put wordcount /spark/input
三、指令命令
A、Spark on Mesos运行模式
1、在ndoe180节点上运行Spark-Shell测试
/opt/module/spark-3.0.0-hadoop3.2/bin
./spark-shell --master spark://node180:7077
scala> val mapRdd=sc.textFile("/spark/input").flatMap(_.split(" ")).map(word=>(word,1)).reduceByKey(_+_).map(entry=>(entry._2,entry._1))
mapRdd: org.apache.spark.rdd.RDD[(Int, String)] = MapPartitionsRDD[5] at map at <console>:24
#下面的排序如果设置并行度为2则内存被撑爆，因为每个Executor(Task(JVM))的最小内存是480MB,并行度为2就表示所需内存在原有的基础上翻一倍
scala> val sortRdd=mapRdd.sortByKey(false,1)
sortRdd: org.apache.spark.rdd.RDD[(Int, String)] = ShuffledRDD[6] at sortByKey at <console>:26
scala> val mapRdd2=sortRdd.map(entry=>(entry._2,entry._1))
mapRdd2: org.apache.spark.rdd.RDD[(String, Int)] = MapPartitionsRDD[7] at map at <console>:28
#下面这个存储步骤也是非常消耗内存的
scala> mapRdd2.saveAsTextFile("/spark/output")
scala> :quit
或
sc.textFile("/spark/input").flatMap(_.split(" ")).map(word=>(word,1)).reduceByKey(_+_).map(entry=>(entry._2,entry._1)).sortByKey(false,1).map(entry=>(entry._2,entry._1)).saveAsTextFile("/spark/output")
回车执行命令如下：
解释：
sc(Spark context available as 'sc' )
textFile(读取文件)
line1
line2
line3
_.split(" ")
[[word1,word2,word],[word1,word3,word],[word1,word4,word]]
flatmap(扁平化)
[word1,word2,word,word1,word2,word,word1,word2,word]
map(一个map任务，计算)
(word1,1),(word2,1),(word,1),(word1,1),(word3,1),(word,1),(word1,1),(word4,1),(word,1)
reduceByKey(通过key统计)
[(word1,3),(word2,1),(word,3),(word3,1),(word4,1)]
map(一个map任务，交换顺序)
[(3,word1),(1,word2),(3,word),(1,word3),(1,word4)]
sortByKey(根据key排序，排序如果设置并行度为2则内存被撑爆，因为每个Executor(Task(JVM))的最小内存是480MB,并行度为2就表示所需内存在原有的基础上翻一倍)
[(1,word2),(1,word3),(1,word4),(3,word1),(3,word)]
map(一个map任务，交换顺序)
[(word2,1),(word3,1),(word4,1),(word1,3),(word,3)]
saveAsTextFile(保存到指定目录)
查看HDFS集群中是否已经存在数据
hdfs dfs -ls /spark/output
控制台打开文件
hdfs dfs -cat /spark/output/part-00000
2、以Spark on Mesos模式运行Spark-Submit，指定master参数为spark://node180:7077
spark-submit --class org.apache.spark.examples.JavaSparkPi --master spark://node180:7077 ../examples/jars/spark-examples_2.12-3.0.0-preview2.jar
