fuse-dfs掛載全過程

fuse-dfs掛載全過程   fuse-dfs掛載終於成功了,斷斷續續弄了兩周多,而最後的一步掛載出錯花了我一周時間,加了個HDFS QQ群問了之後才知道哪裡弄錯了,且聽細細道來。   fuse-dfs掛載全過程   准備工作:   CentOS 6.3,Hadoop 1.2.0, jdk 1.6.0_45,fuse 2.8.4,ant 1.9.1   1.安裝fuse   yum install fuse fuse-libs fuse-devel     2.安裝ant   官網下載,解壓   3.系統配置   vi /etc/profile   最後添加:   export OS_ARCH=i386     #如果是64位機器填amd64 export OS_BIT=32      #64 export JAVA_HOME=/usr/java/jdk1.6.0_45 export ANT_HOME=/usr/ant export PATH=$JAVA_HOME/bin:$ANT_HOME/bin:$PATH export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$HADOOP_HOME/lib:$HADOOP_HOME:$CLASSPATH export HADOOP_HOME=/usr/hadoop export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/$OS_ARCH/server:$HADOOP_HOME/c++/Linux-$OS_ARCH-$OS_BIT/lib:/usr/local/lib:/usr/lib   退出,編譯 source /etc/profile   4.編譯libhdfs   cd $HADOOP_HOME ant compile-c++-libhdfs -Dlibhdfs=1 -Dcompile.c++=1 ln -s c++/Linux-$OS_ARCH-$OS_BIT/lib build/libhdfs ant compile-contrib -Dlibhdfs=1 -Dfusedfs=1   (提示:1.如果編譯沒通過,缺少依賴包,yum install automakeautoconf m4 libtool pkgconfig fuse fuse-devel fuse-libs 2.在安裝的過程中還要安裝gcc 。編譯成功會提示 build successful,看到這句心情非常愉悅)   5.環境配置   cd $HADOOP_HOME/build/contrib/fuse-dfs vi fuse_dfs_wrapper.sh 在文件最前面添加: export JAVA_HOME=/usr/java/jdk1.6.0_45 export HADOOP_HOME=/usr/hadoop export HADOOP_CONF_DIR=/usr/hadoop/conf export OS_ARCH=i386 export OS_BIT=32 把最後一句“./fuse_dfs$@” 改成 “fuse_dfs@”   6.添加權限   $chmod +x /usr/hadoop/build/contrib/fuse-dfs/fuse_dfs_wrapper.sh  $chmod +x  /usr/hadoop/build/contrib/fuse-dfs/fuse_dfs  $ln -s  /usr/hadoop/build/contrib/fuse-dfs/fuse_dfs_wrapper.sh /usr/local/bin  $ln -s  /usr/hadoop/build/contrib/fuse-dfs/fuse_dfs /usr/local/bin/   7.掛載   mkdir /mnt/dfs cd $HADOOP_HOME/build/contrib/fuse-dfs fuse_dfs_wrapper.sh dfs://localhost:9000 /mnt/dfs (就是這最後一步!!糊弄了我一周!!關於fuse_dfs_wrapper.sh後面跟的這個鏈接,我一直遵循)conf/core-site.xml裡設置的value值:hdfs://localhost:9000,一直報錯fuse-dfs didn't recognize hdfs://localhost:9000,-2  fuse-dfs didn't recognize /mnt/dfs,-2 )   最後ls /mnt/dfs就可以看到hdfs裡的文件了
