OS / XにHadoopネイティブライブラリが見つかりません

Githubからhadoopソースコードをダウンロードし、nativeオプションを使用してコンパイルしました。

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

次に、.dylibファイルを$ HADOOP_HOME/libに

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

LD_LIBRARY_PATHが更新され、hdfsが再起動されました。

 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：これは、Docker-sparkでの Hadoop「プラットフォームのネイティブHadoopライブラリをロードできません」エラー）への回答が意味することも意味しますか？ が機能しません。

ただし、checknativeは引き続き均一にfalseを返します。

MacOS 10.12の新規インストールでこれを機能させるには、以下を実行する必要がありました。

  1. homebrew を使用してビルドの依存関係をインストールします。

    brew install cmake maven openssl [email protected] snappy

  2. Hadoopのソースコードを確認する

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

  3. 以下のパッチをビルドに適用します。

  4. ソースからhadoopをビルドします。

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

  5. Hadoopの実行時にJava_LIBRARY_PATHを指定します。

    $ Java_LIBRARY_PATH=/usr/local/opt/openssl/lib:/opt/local/lib:/usr/lib hadoop-dist/target/hadoop-2.7.3/bin/hadoop checknative -a

上記の@andrewdotnの応答に欠けているステップがあります：

1）ステップ（3）では、テキストファイルに投稿されたテキストを追加してパッチを作成します。 「patch.txt」、「git apply patch.txt」の順に実行します

2）javadbaの指示に従ってファイルをコピーすることに加えて、特定のアプリケーションでは、次の設定も必要です。

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

必要な手順は、*.dylibをgitソースビルドディレクトリからプラットフォームの$HADOOP_HOME/<common dir>libディレクトリにコピーすることです。 brew経由でインストールされたOS/Xの場合：

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

ここで必要なライブラリを確認できます。

$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

そしてhadoop checknativeコマンドが機能するようになりました：

$hadoop checknative
