Hadoop native libraries not found on OS/X

The needed step is to copy the *.dylib from the git sources build dir into the $HADOOP_HOME/<common dir>lib dir for your platform . For OS/X installed via brew it is:

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

We can see the required libs there now:

$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

And now the hadoop checknative command works:

$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.

There are some missing steps in @andrewdotn's response above:

1) For step (3), create the patch by adding the text posted to a text file e.g. "patch.txt", and then execute "git apply patch.txt"

2) In addition to copying the files as directed by javadba, certain applications also require that you set:

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

To get this working on a fresh install of macOS 10.12, I had to do the following:

  1. Install build dependencies using homebrew:

    brew install cmake maven openssl [email protected] snappy
    
  2. Check out hadoop source code

    git clone https://github.com/apache/hadoop.git
    cd hadoop
    git checkout rel/release-2.7.3
    
  3. Apply the below patch to the build:
