Hadoop nativen Bibliotheken nicht auf OS gefunden/X

Question

I hadoop Quellcode von Github heruntergeladen haben, und mit der native Option kompiliert:

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

ich dann kopiert die .dylib Dateien auf die $ 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 

Die LD_LIBRARY_PATH wurde aktualisiert und neu gestartet 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 

(Anmerkung: Dies bedeutet auch, dass die Antwort auf Hadoop “Unable to load native-hadoop library for your platform” error on docker-spark? nicht für mich arbeiten ..)

Aber checknative noch gibt gleichmäßig false:

Answer 1

Um diese Arbeit auf eine neue installation von macOS 10.12, musste ich folgendes tun:

1. Bauabhängigkeiten Installieren homebrew mit:

   brew install cmake maven openssl protobuf@2.5 snappy 
   

2. Check out hadoop Quellcode

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

3. den unten Patch Build Nehmen:

4. Build-hadoop aus Quelle:

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

5. JAVA_LIBRARY_PATH Geben Sie bei hadoop ausgeführt wird:

   $ 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

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

Answer 2

Der benötigten Schritt ist die *.dylib aus den git Quellen kopieren bau dir in das $HADOOP_HOME/<common dir>lib Verzeichnis für deine Plattform. Für OS/X über brew installiert ist:

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

Wir haben jetzt die benötigten Libs dort sehen können:

$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 

Und nun die hadoop checknative Befehl funktioniert:

$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. 

Answer 3

Es gibt einige fehlenden Schritte in @ andrewdotn Antwort oben:

1) Bei Schritt (3), erstellen Sie den Patch indem Sie den Text hinzufügen, der in eine Textdatei geschrieben wurde, z "patch.txt" und dann "git apply patch" ausführen.txt“

2) Zusätzlich zum Kopieren der Dateien wie von javadba gerichtet, auch bestimmte Anwendungen erfordern, dass Sie Folgendes einstellen:

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 

Answer 4

als Update Antwort auf @andrewdotn, hier ist die patch.txt Datei verwendet werden mit Hadoop 2.8.1:
