fuse-dfs挂载hdfs实录

标签：hdfs   hadoop   fuse-dfs   

部署安装了最新稳定版hadoop2.2.0，然后在网上找来fuse-dfs编译教程，但是最后失败了，至今原因未知～～，错误描述为：Transport endpoint is not connected。后将安装部署hadoop1.2.1版本，最后测试成功，记录如下：

使用root完成一下操作：

1、安装依赖包

apt-get install autoconf automake libtool make gawk g++ ant

apt-get purge fuse
apt-get purge libfuse2
tar -zxf fuse-2.9.3.tar.gz
cd fuse-2.9.3
./configure --prefix=/usr/fuse
make
make install

ln -s  /usr/fuse/bin/fusermount /usr/bin/

 vi /etc/profile

export FUSE_HOME=/usr/fuse
export OS_ARCH=amd64
export OS_BIT=64
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/$OS_ARCH/server:${HADOOP_HOME}/build/c++/Linux-$OS_ARCH-$OS_BIT/lib:/usr/local/lib:/usr/lib:$FUSE_HOME/lib

source /etc/profile

cd $HADOOP_HOME/
ant compile-c++-libhdfs -Dlibhdfs=1 -Dcompile.c++=1
ln -s c++/Linux-$OS_ARCH-$OS_BIT/lib build/libhdfs

ln -s /usr/fuse/include/* /usr/include/
ln -s /usr/fuse/lib/libfuse.so /usr/lib/
ant compile-contrib -Dlibhdfs=1 -Dfusedfs=1

编辑fuse_dfs_wrapper.sh，vi $HADOOP_HOME/build/contrib/fuse-dfs/fuse_dfs_wrapper.sh加上环境参数，尾行修改如下：

export JAVA_HOME=<你的javahome>
export HADOOP_HOME=<你的hadoophome>
export FUSE_HOME=/usr/fuse
export PATH=$PATH:$HADOOP_HOME/contrib/fuse_dfs
for f in ls $HADOOP_HOME/lib/*.jar $HADOOP_HOME/*.jar
do
export  CLASSPATH=$CLASSPATH:$f
done
export OS_ARCH=amd64
export OS_BIT=64
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/$OS_ARCH/server:${HADOOP_HOME}/build/c++/Linux-$OS_ARCH-$OS_BIT/lib:/usr/local/lib:/usr/lib:$FUSE_HOME/lib

fuse_dfs $@

修改fuse_dfs_wrapper.sh权限

chmod 755  ${HADOOP_HOME}/build/contrib/fuse-dfs/fuse_dfs_wrapper.sh

ln -s ${HADOOP_HOME}/build/contrib/fuse-dfs/fuse_dfs_wrapper.sh /usr/local/bin
ln -s ${HADOOP_HOME}/build/contrib/fuse-dfs/fuse_dfs /usr/local/bin/ 

mkdir -p /mnt/dfs
fuse_dfs_wrapper.sh dfs://localhost:9005 /mnt/dfs

卸载hdfs

umount /mnt/dfs

1、执行步骤5的时候，出现undefined reference to fuse_get_context等一些列的错误。复制执行错误的命令，将-L和-l参数放到组后，运行可能会出现undefined reference to symbol ‘floor@@GLIBC_2.2.5‘的错误，那么最后添加-lm参数，问题解决。然后重新执行编译

2、commons-logging#commons-logging;1.0.4: not found错误。修改ivy/libraries.properties文件的commons-logging.version=1.1.1即可。

3、执行挂载的时候一定要将地址输正确，包括主机名和端口号。否则会出现读写错误的问题。
