hadoop2.2.0 jdk1.7 tachyon0.5.0 无zookeeper
tachyon和hadoop都是伪分布式模式
1.修改core-site.xml文件
<property> <name>fs.tachyon.impl</name> <value>tachyon.hadoop.TFS</value> </property>
2.配置hadoop-env.sh
在hadoop-env.sh文件中添加Tachyon客户端jar包路径的环境变量
export HADOOP_CLASSPATH=/home/hadoop/tachyon-0.5.0-bin/client/target/tachyon-client-0.5.0-jar-with-dependencies.jar
3.启动hadoop集群
sbin/start-dfs.sh
sbin/start-yarn.sh
4.启动tachyon
tachyon-start.sh local
5.执行MR作业
hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar wordcount -libjars /home/hadoop/tachyon-0.5.0-bin/client/target/tachyon-client-0.5.0-jar-with-dependencies.jar tachyon://hadoop:19998/test/passwd tachyon://hadoop:19998/out
6.查看结果
tachyon tfs cat /out/part-r-00000
