1.解压
tar zxvf alluxio-1.4.0-cdh5-bin.tar.gz
2.配置
cd alluxio-1.4.0/conf
2.1
为实现持久化，创建hdfs目录，并配置相关设置
hdfs dfs -mkdir /alluxio

3. 格式化，并启动服务
cd ../bin
alluxio copyDir /home/user/alluxio-1.4.0
alluxio format
alluxio-start.sh all NoMount
4.cd ../libexec
vi alluxio-config.sh
export JAVA_HOME=/usr/java/default
source /etc/profile
5. cd ../..
scp -r alluxio-1.4.0 [email protected]:/home/user
scp -r alluxio-1.4.0 [email protected]:/home/user
6. 启动所有服务
bin/alluxio-stop.sh all
bin/alluxio-start.sh all
7. 使用
alluxio --help
alluxio fs checkConsistency hdfs://10.88.1.86:8020/alluxio
从本地拷贝文件
alluxio fs copyFromLocal worker.out /
持久化
alluxio fs persist /worker.out
HDFS查看持久化结果
hdfs dfs -ls /alluxio
结束持久化
alluxio fs free /worker.out
HDFS查看结束持久化结果
hdfs dfs -ls /alluxio
下载文件
alluxio fs load /worker.out
alluxio fs -ls
alluxio fs rm /worker.out
alluxio fs ls /
hdfs dfs -ls /alluxio
