I have downloaded hadoop
source code from github and compiled with the native
option:
mvn package -Pdist,native -DskipTests -Dtar -Dmaven.javadoc.skip=true
I then copied the .dylib
files to the $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
The LD_LIBRARY_PATH was updated and hdfs restarted:
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
(Note: this also means that the answer to Hadoop “Unable to load native-hadoop library for your platform” error on docker-spark? does not work for me..)
But checknative
still returns uniformly false
:
$stop-dfs.sh && start-dfs.sh && hadoop checknative
