hadoop安装完成后基准测试

1） 测试HDFS写性能

       测试内容：向HDFS集群写10个128M的文件

[[email protected] mapreduce]$ hadoop jar /opt/module/hadoop-3.1.3/share/hadoop/mapreduce/hadoop-mapreduce-client-jobclient-3.1.3-tests.jar TestDFSIO -write -nrFiles 10 -fileSize 128MB



2020-04-16 13:41:24,724 INFO fs.TestDFSIO: ----- TestDFSIO ----- : write

2020-04-16 13:41:24,724 INFO fs.TestDFSIO:             Date & time: Thu Apr 16 13:41:24 CST 2020

2020-04-16 13:41:24,724 INFO fs.TestDFSIO:         Number of files: 10

2020-04-16 13:41:24,725 INFO fs.TestDFSIO:  Total MBytes processed: 1280

2020-04-16 13:41:24,725 INFO fs.TestDFSIO:       Throughput mb/sec: 8.88

2020-04-16 13:41:24,725 INFO fs.TestDFSIO:  Average IO rate mb/sec: 8.96

2020-04-16 13:41:24,725 INFO fs.TestDFSIO:   IO rate std deviation: 0.87

2020-04-16 13:41:24,725 INFO fs.TestDFSIO:      Test exec time sec: 67.61
           

2）测试HDFS读性能

测试内容：读取HDFS集群10个128M的文件

[[email protected] mapreduce]$ hadoop jar /opt/module/hadoop-3.1.3/share/hadoop/mapreduce/hadoop-mapreduce-client-jobclient-3.1.3-tests.jar TestDFSIO -read -nrFiles 10 -fileSize 128MB



2020-04-16 13:43:38,857 INFO fs.TestDFSIO: ----- TestDFSIO ----- : read

2020-04-16 13:43:38,858 INFO fs.TestDFSIO:   Date & time: Thu Apr 16 13:43:38 CST 2020

2020-04-16 13:43:38,859 INFO fs.TestDFSIO:         Number of files: 10

2020-04-16 13:43:38,859 INFO fs.TestDFSIO:  Total MBytes processed: 1280

2020-04-16 13:43:38,859 INFO fs.TestDFSIO:       Throughput mb/sec: 85.54

2020-04-16 13:43:38,860 INFO fs.TestDFSIO:  Average IO rate mb/sec: 100.21

2020-04-16 13:43:38,860 INFO fs.TestDFSIO:   IO rate std deviation: 44.37

2020-04-16 13:43:38,860 INFO fs.TestDFSIO:      Test exec time sec: 53.61
           

3）删除测试生成数据

[[email protected] mapreduce]$ hadoop jar /opt/module/hadoop-3.1.3/share/hadoop/mapreduce/hadoop-mapreduce-client-jobclient-3.1.3-tests.jar TestDFSIO -clean

           

4）使用Sort程序评测MapReduce

（1）使用RandomWriter来产生随机数，每个节点运行10个Map任务，每个Map产生大约1G大小的二进制随机数

[[email protected] mapreduce]$ hadoop jar /opt/module/hadoop-3.1.3/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.1.3.jar randomwriter random-data

           

（2）执行Sort程序

[[email protected] mapreduce]$ hadoop jar /opt/module/hadoop-3.1.3/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.1.3.jar sort random-data sorted-data

           

（3）验证数据是否真正排好序了

[[email protected] mapreduce]$

hadoop jar /opt/module/hadoop-3.1.3/share/hadoop/mapreduce/hadoop-mapreduce-client-jobclient-3.1.3-tests.jar testmapredsort -sortInput random-data -sortOutput sorted-data
