在OS / X上找不到Hadoop本机库

标签： macos hadoop nativelibrary

我从github下载了hadoop源代码，并使用native选项进行了编译：

mvn package -Pdist,native -DskipTests -Dtar -Dmaven.javadoc.skip=true

然后我将.dylib文件复制到$ HADOOP_HOME / lib 

cp -p hadoop-common-project/hadoop-common/target/hadoop-common-2.7.1/lib/native/*.dylib /usr/local/Cellar/hadoop/2.7.2/libexec/share/hadoop/lib

更新了LD_LIBRARY_PATH并重新启动了hdfs：

 echo $LD_LIBRARY_PATH
 /usr/local/Cellar/hadoop/2.7.2/libexec/lib:
 /usr/local/Cellar/hadoop/2.7.2/libexec/share/hadoop/common/lib:/Library/Java/JavaVirtualMachines/jdk1.8.0_92.jdk/Contents/Home//jre/lib

（注意：这也意味着Hadoop “Unable to load native-hadoop library for your platform” error on docker-spark?的答案对我不起作用..）

但checknative仍然统一返回false：

$stop-dfs.sh && start-dfs.sh && hadoop checknative

为了使这项工作全新安装macOS 10.12，我必须执行以下操作：

  1. 使用homebrew安装构建依赖项：

    brew install cmake maven openssl protobuf@2.5 snappy

  2. 查看hadoop源代码

    git clone https://github.com/apache/hadoop.git
cd hadoop
git checkout rel/release-2.7.3

  3. 将以下补丁应用于构建：

    diff --git a/hadoop-common-project/hadoop-common/src/CMakeLists.txt b/hadoop-common-project/hadoop-common/src/CMakeLists.txt
index 942b19c..8b34881 100644

  4. 从源代码构建hadoop：

    mvn package -Pdist,native -DskipTests -Dtar -Dmaven.javadoc.skip=true

  5. 运行hadoop时指定JAVA_LIBRARY_PATH：

    $ JAVA_LIBRARY_PATH=/usr/local/opt/openssl/lib:/opt/local/lib:/usr/lib hadoop-dist/target/hadoop-2.7.3/bin/hadoop checknative -a
16/10/14 20:16:32 INFO bzip2.Bzip2Factory: Successfully loaded & initialized native-bzip2 library libbz2.dylib

lz4:     true revision:99
bzip2:   true /usr/lib/libbz2.1.0.dylib
openssl: true /usr/local/opt/openssl/lib/libcrypto.dylib

答案 1 :(得分：5)

@ andrewdotn上面的回复中有一些缺失的步骤：

1）对于步骤（3），通过添加发布到文本文件的文本来创建补丁，例如“patch.txt”，然后执行“git apply patch.txt”

2）除了按照javadba的指示复制文件外，某些应用程序还要求您设置：

export HADOOP_OPTS="-Djava.library.path=${HADOOP_HOME}/lib/native"
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${HADOOP_HOME}/lib/native
export JAVA_LIBRARY_PATH=$JAVA_LIBRARY_PATH:${HADOOP_HOME}/lib/native

答案 2 :(得分：1)

所需步骤是将*.dylib来源构建目录中的git复制到您平台的$HADOOP_HOME/<common dir>lib目录中。对于通过OS/X安装的brew，它是：

cp /git/hadoop/hadoop-dist/target/hadoop-2.7.1/lib/native/ /usr/local/Cellar/hadoop/2.7.2/libexec/share/hadoop/common/

我们现在可以看到所需的库：

$ll /usr/local/Cellar/hadoop/2.7.2/libexec/share/hadoop/common/*.dylib
-rwxr-xr-x  1 macuser  staff  149100 Jun 13 13:44 /usr/local/Cellar/hadoop/2.7.2/libexec/share/hadoop/common/libhadoop.dylib
-rwxr-xr-x  1 macuser  staff  149100 Jun 13 13:44 /usr/local/Cellar/hadoop/2.7.2/libexec/share/hadoop/common/libhadoop.1.0.0.dylib

现在hadoop checknative命令有效：

$hadoop checknative

6/06/15 09:10:59 INFO zlib.ZlibFactory: Successfully loaded & initialized native-zlib library
Native library checking:
hadoop:  true /usr/local/Cellar/hadoop/2.7.2/libexec/share/hadoop/common/libhadoop.dylib
zlib:    true /usr/lib/libz.1.dylib
snappy:  false
lz4:     true revision:99
bzip2:   false
openssl: false build does not support openssl.
