hadoop-native-library

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/

I am trying to use OpenCV with Hadoop. Below is my code. I am just testing if OpenCV libraries works fine with Hadoop, i.e when I am running OpenCV code in function public int run(String[] args) of Hadoop. I searched on the internet, and found some ways of how to add OpenCV native library ( libopencv_java310.so ) in Hadoop. I tried some ways, but it didn't work. For example this tutorial . It says add JAVA.LIBRARY.PATH to hadoop-config.sh file. But it didn't work. I got this error Exception in thread "main" java.lang.UnsatisfiedLinkError: no opencv_java310 in java.library.path at line System
