Hadoop librerie native non trovato su OS/X

Question

Ho scaricato hadoop codice sorgente da github e compilato con l'opzione native:

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

Poi ho copiato le lime .dylib al $ 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 

La LD_LIBRARY_PATH è stato aggiornato e HDFS riavviato:

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 

(Nota: questo significa anche che la risposta a Hadoop “Unable to load native-hadoop library for your platform” error on docker-spark? non funziona per me ..)

Ma checknative restituisce ancora uniformemente false:

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

Answer 1

per ottenere questo lavoro su una nuova installazione di macOS 10.12, ho dovuto fare quanto segue:

1. Installare le dipendenze di compilazione utilizzando homebrew:

   brew install cmake maven openssl protobuf@2.5 snappy 
   

2. Partenza Hadoop codice sorgente

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

3. applicare la patch di seguito per la compilazione:

   diff --git a/hadoop-common-project/hadoop-common/src/CMakeLists.txt b/hadoop-common-project/hadoop-common/src/CMakeLists.txt

4. costruire Hadoop da fonte:

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

5. Specificare JAVA_LIBRARY_PATH durante l'esecuzione di Hadoop:

   $ 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 
   16/10/14 20:16:32 INFO zlib.ZlibFactory: Successfully loaded & initialized native-zlib library 
   Native library checking: 
   hadoop: true /Users/admin/Desktop/hadoop/hadoop-dist/target/hadoop-2.7.3/lib/native/libhadoop.dylib 
   zlib: true /usr/lib/libz.1.dylib 
   snappy: true /usr/local/lib/libsnappy.1.dylib 
   lz4:  true revision:99 
   bzip2: true /usr/lib/libbz2.1.0.dylib 
   openssl: true /usr/local/opt/openssl/lib/libcrypto.dylib 
   

Answer 2

Il passo necessario è quello di copiare il *.dylib dalle git fonti costruire dir nella directory $HADOOP_HOME/<common dir>lib per la tua piattaforma. Per OS/X installato tramite brew è:

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

possiamo vedere le librerie necessarie lì adesso:

$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 

E ora i hadoop checknative comando funziona:

$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

Ci sono alcuni passaggi mancanti in @ di andrewdotn risposta di cui sopra:

1) Per il passaggio (3), creare la patch aggiungendo il testo inviato ad un file di testo es "patch.txt", quindi eseguire "git apply patch.txt"

2) Oltre a copiare i file come indicato dal javadba, alcune applicazioni richiedono di impostare:

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

come aggiornamento di @andrewdotn risposta, qui è il file patch.txt da utilizzare con Hadoop 2.8.1:
