Hadoop-MapReduce+Yarm部署
Hadoop-MapReduce+Yarm部署
1.Yarn部署
[[email protected] hadoop]$ cd etc/hadoop/
[[email protected] hadoop]$ cp mapred-site.xml.template mapred-site.xml
先備份
<configuration>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>
[[email protected] hadoop]$ vi yarn-site.xml
<configuration>
<!-- Site specific YARN configuration properties -->
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
</configuration>
[[email protected] hadoop]$ cd ../
[
[[email protected] hadoop]$ cd sbin/
[[email protected] sbin]$ ./start-yarn.sh
web介面: http://192.168.40.130:8088/
2.MR Job測試
MapReduce: java程式碼寫的，map(對映)函式和reduce(歸約)函式
[[email protected] sbin]$ cd ../
[[email protected] hadoop]$ find ./ -name "*example*"
./lib/native/examples
\./share/hadoop/mapreduce/hadoop-mapreduce-examples-2.8.1.jar
./share/hadoop/mapreduce/lib-examples
./share/hadoop/mapreduce/sources/hadoop-mapreduce-examples-2.8.1-test-sources.jar
./share/hadoop/mapreduce/sources/hadoop-mapreduce-examples-2.8.1-sources.jar
./etc/hadoop/ssl-server.xml.example
./etc/hadoop/ssl-client.xml.example
[[email protected] hadoop]$ bin/hadoop jar ./share/hadoop/mapreduce/hadoop-mapreduce-examples-2.8.1.jar pi 5 10
Number of Maps = 5
