Fuse-dfs mounting process preparation: CentOS 6.3, Hadoop 1.2.0, jdk 1.6.0 _ 45, fuse 2.8.4, ant 1.9.1 1. install fuse yum install fuse-libs fuse-devel 2. download the ant official website and decompress the package. add vi/etc/profile at the end of the system configuration: export OS _ARCH = i386 # amd64export OS _BIT = 32 #64 export JAVA_HOME =/usr/java/jdk1.6.0 _ 45 export ANT_HOME =/usr/antexport PATH = $ JAVA_HOME/ bin: $ ANT_HOME/bin: $ PATHexport CLASSPATH =.: $ JAVA_HOME/lib/dt. jar: $ JAVA_HOME/lib/tools. jar: $ HADOOP_HOME/lib: $ HADOOP_HOME: $ CLASSPATHexport HADOOP_HOME =/usr/hadoopexport LD_LIBRARY_PATH = $ JAVA_HOME/jre/lib/$ OS _ARCH/server: $ HADOOP_HOME/c ++/Linux-$ OS _ARCH-$ OS _BIT/lib:/usr/local/lib:/usr/lib exit, compile source/etc/profile 4. compile libhdfs cd $ HADOOP_HOMEant compile-c ++-libhdfs-Dlibhdfs = 1-Dcompile. c ++ = 1ln-s c ++/Linux-$ OS _ARCH-$ OS _BIT/lib build/libhdfsant compile-contrib-Dlibhdfs = 1-Dfusedfs = 1 (note: 1. If the compilation fails, the dependency package is missing, yum install automakeautoconf m4 libtool pkgconfig fuse-devel fuse-libs2. gcc will also be installed during installation. If the compilation is successful, the system prompts build successful. the sentence is very pleasant.) 5. environment configuration cd $ HADOOP_HOME/build/contrib/fuse-dfsvi fuse_dfs_wrapper.sh add at the beginning of the file: export JAVA_HOME =/usr/java/jdk1.6.0 _ 45 export HADOOP_HOME =/usr/hadoopexport export =/usr/hadoop/confexport OS _ARCH = imo-export OS _BIT = 32. /change fuse_dfs $ @ to "fuse_dfs @" 6. add permissions $ chmod + x/usr/hadoop/build/contrib/fuse-dfs/fuse_dfs_wrapper.sh $ chmod + x/usr/hadoop/build/contrib/fus E-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. mount mkdir/mnt/dfscd $ HADOOP_HOME/build/contrib/fuse-dfsfuse_dfs_wrapper.sh dfs: // localhost: 9000/mnt/dfs (that's the last step !! Fooled me for a week !! For the link behind fuse_dfs_wrapper.sh, I have always followed the value set in the conf/core-site.xml: hdfs: // localhost: 9000, which has always reported the error fuse-dfs didn't recognize hdfs: // localhost: 9000,-2 fuse-dfs didn't recognize/mnt/dfs,-2) finally, ls/mnt/dfs can see the files in hdfs.
