1） 測試HDFS寫效能
測試內容：向HDFS叢集寫10個128M的檔案
[[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）測試HDFS讀效能
測試內容：讀取HDFS叢集10個128M的檔案
[[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）刪除測試生成資料
[[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程式評測MapReduce
（1）使用RandomWriter來產生隨機數，每個節點執行10個Map任務，每個Map產生大約1G大小的二進位制隨機數
[[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）執行Sort程式
[[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）驗證資料是否真正排好序了
[[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
