hdfs mount为linux本地文件系统

1、软件下载

hdfs-webdav.war

http://code.google.com/p/hdfs-webdav/downloads/list

把war包放到tomcat下面，启动tomcat会自动解压该war包，在/usr/tomcat6/webapps/hdfs-webdav/linux_mount_lib/目录下有fuse-2.7.4.tar.gz和neon-0.28.3.tar.gz，所以下面的包也可以不用下载

?

neon

http://www.webdav.org/neon/neon-0.29.6.tar.gz

fuse

http://sourceforge.net/projects/fuse/files/fuse-2.X/2.8.7/

2、软件安装

yum install gcc

yum install libxml*

tar -zxvf neon-0.28.3.tar.gz

cd /usr/tomcat6/webapps/hdfs-webdav/linux_mount_lib/neon-0.28.3

./configure

make

make install

?

cd ..

tar zxvf davfs2-1.3.3.tar.gz

cd davfs2-1.3.3

./configure

make

make install

?

cd ..

tar zxvf fuse-2.7.4.tar.gz

cd fuse-2.7.4
./configure
make
make install

vim /usr/tomcat6/webapps/hdfs-webdav/WEB-INF/classes/hadoop-site.xml

?<property>
?? <name>fs.default.name</name>
?? <value>hdfs://10.0.30.235:9000/</value>
?? <description>namenode</description>
?</property>

?

scp 10.0.30.151:/download/hadoop-0.20.203.0/hadoop-core-0.20.203.0.jar /usr/tomcat6/webapps/hdfs-webdav/WEB-INF/lib/

并删除掉lib目录下旧的hadoop jar包

?

scp 10.0.30.151:/download/hadoop-0.20.203.0/lib/commons-configuration-1.6.jar /usr/tomcat6/webapps/hdfs-webdav/WEB-INF/lib

?

启动hadoop集群

?

启动tomcat

访问http://113.105.131.240/hdfs-webdav

?

在tomcat服务器上创建一下信息

mkdir /download/hdfs
groupadd davfs2
useradd -g davfs2 davfs2
mount -t davfs http://10.0.30.151/hdfs-webdav /download/hdfs
cd /download/hdfs

ls

?

至此，扩展hadoop hdfs,实现WebDav协议,并将hdfs mount为linux本地文件系统成功！
