编译hadoop的libhdfs.a

进入hadoop-hdfs-project/hadoop-hdfs/src目录，执行cmake以生成Makefile文件。 如果遇到如下的错误： ~/hadoop-2.7.1-src/hadoop-hdfs-project/hadoop-hdfs/src]$ cmake . JAVA_HOME=, JAVA_JVM_LIBRARY=/data/jdk/jre/lib/amd64/server/libjvm.so JAVA_INCLUDE_PATH=/data/jdk/include, JAVA_INCLUDE_PATH2=/data/jdk/include/linux Located all JNI components successfully. CMake Error at CMakeLists.txt:84 (MESSAGE):   You must set the CMake variable GENERATED_JAVAH -- Configuring incomplete, errors occurred! 则指定一下cmake参数即可，如下所示： cmake -DJAVA_HOME=/data/jdk -DGENERATED_JAVAH=/data/jdk . 然后带参数再次执行cmake： ~/hadoop-2.7.1-src/hadoop-hdfs-project/hadoop-hdfs/src]$ cmake -DJAVA_HOME=/data/jdk -DGENERATED_JAVAH=/data/jdk . 下面的显示表示cmake成功，会在当前目录下生成Makefile文件： JAVA_HOME=/data/jdk, JAVA_JVM_LIBRARY=/data/jdk/jre/lib/amd64/server/libjvm.so JAVA_INCLUDE_PATH=/data/jdk/include, JAVA_INCLUDE_PATH2=/data/jdk/include/linux Located all JNI components successfully. -- Found PkgConfig: /usr/bin/pkg-config (found version "0.23")  -- checking for module 'fuse' --   package 'fuse' not found -- Failed to find Linux FUSE libraries or include files.  Will not build FUSE client. -- Configuring done -- Generating done -- Build files have been written to: /data/hadoop-2.7.1-src/hadoop-hdfs-project/hadoop-hdfs/src 接下来就可以执行make来编译生成libhdfs.a了。
