Fuse-DFS Mount HDFS record

The latest stable version of hadoop2.2.0 is deployed and installed, and the fuse-DFS compilation tutorial is found on the Internet, but the final failure occurs. The cause is unknown ~~, Error Description: transport endpoint is not connected. Hadoop1.2.1 will be installed and deployed, and the test is successful. The record is as follows:

Use root to complete the following operations:

1. Install the dependency package

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

2. Uninstall existing fuse and install Fuse

apt-get purge fuseapt-get purge libfuse2tar -zxf fuse-2.9.3.tar.gzcd fuse-2.9.3./configure --prefix=/usr/fusemakemake install

3. Set Environment Variables

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

 vi /etc/profile

export FUSE_HOME=/usr/fuseexport OS_ARCH=amd64export OS_BIT=64export 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

4. Compile libhdfs, fuse-DFS, and HDFS Interfaces

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

5. Compile fuse-DFS

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

6. Attach HDFS to a local device

Edit fuse_dfs_wrapper.sh, VI $ hadoop_home/build/contrib/fuse-DFS/fuse_dfs_wrapper.sh, and add the environment parameters. Modify the end line as follows:

Export java_home = <your javahome> export hadoop_home = <your hadoophome> export fuse_home =/usr/fuseexport Path = $ path: $ hadoop_home/contrib/fuse_dfsfor F in ls $ hadoop_home/lib /*. jar $ hadoop_home /*. jardoexport classpath = $ classpath: $ fdoneexport OS _arch = amd64export 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

End modification:

Modify fuse_dfs_wrapper.sh permission

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

Create Link

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

Mount HDFS to a local device

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

Note: localhost: 9005 is the value of FS. Default. name in the hadoop core-site.xml configuration file, followed by "DFS"

Uninstall HDFS

umount /mnt/dfs

Appendix:

1. When Step 5 is executed, some columns such as undefined reference to fuse_get_context are incorrect. Copy and execute the wrong command, put the-L and-l parameters in the group, and run the undefined reference to symbol' [email protected] @ glibc_2.2.5 'error, then add the-LM parameter to solve the problem. Then re-execute the compilation

2. commons-logging # commons-logging; 1.0.4: Not Found error. Modify the commons-logging.version of the Ivy/libraries. properties file = 1.1.1.

3. You must enter the correct address, including the host name and port number, during mounting. Otherwise, a read/write error occurs.
