集群环境介绍:
hadoop2.4.1 64位
6台服务器:
hadoop11 NameNode 、SecondaryNameNode
hadoop22 ResourceManager
hadoop33 DataNode、NodeManager
hadoop44 DataNode、NodeManager
hadoop55 DataNode、NodeManager
hadoop66 DataNode、NodeManager
实验1:训练集train.txt样例个数为245057(3.24M) 测试集test.txt样例个数为51444(640kb),并将全部测试集都存放在test.txt中
[root@hadoop11 local]# hadoop fs -lsr /dir6/
-rw-r--r-- 3 root supergroup 3400816 2016-07-17 19:28 /dir6/test.txt
注意:此时所有的测试集都在一个文本中(test.txt)存放,作为输入路径

精确度:51444 51367
CPU time spent (ms)=1045670 (时间之所以长:在于mapper任务的创建花费了时间,并且两个mapper任务都在同一个服务器hadoop66运行)
map tasks=2
实验3:训练集train.txt样例个数为245057不变 测试集test.txt样例个数为51444,并将全部测试集存放在
test1.txt(25402)和test2.txt(15224)和test3.txt(10818)中
[root@hadoop11 local]# hadoop fs -lsr /dir6/
lsr: DEPRECATED: Please use 'ls -R' instead.
-rw-r--r-- 3 root supergroup 128161 2016-07-17 20:54 /dir6/test1.txt

-rw-r--r-- 3 root supergroup 201566 2016-07-17 20:54 /dir6/test3.txt
先看进程日志:
[root@hadoop33 ~]# jps
26501 Jps
26279 YarnChild (mapper任务)
2399 QuorumPeerMain
26280 YarnChild (mapper任务)
23800 DataNode
23648 NodeManager
26133 MRAppMaster
[root@hadoop66 ~]# jps
22777 DataNode
26652 Jps
26302 YarnChild (mapper任务)
22622 NodeManager
此时可以看出,此时mapper任务的执行有两台服务器来执行---分而治之!

总结:MapReduce在处理大数据的时候,会逐渐发挥集群的优势,通过mapper任务的并行处理,提高大数据的处理速度!
