If native libraries are not available the following message is displayed with every hadoop command: hadoop checknative

• Clone hadoop source code

• Checkout the version 2.7.1 source

WARN NativeCodeLoader:60 - Unable to load native-hadoop library for your platform. Using builtin-java classes where applicable I find this very strange, because I know for a fact it uses the same hadoop that I can start on my own without any warnings. There are no other hadoop installations on my computer.

1. May 21, 2015  I have put this issue is from SO, but nobody answer it, so I hope i can get answer here, thanks! I am using docker-spark 1.3.0. After starting spark-shell, it outputs: 15/05/21 04:28:22 DEBUG NativeCodeLoader: Failed to load native-hadoo.
2. Jun 28, 2019 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform. Using builtin-java classes where applicable. My Hadoop Version is 2.2.0. Doing a search online brought up this link. The /native/directory/ on Hadoop 2.x is different so am confused a bit. I have also edited the Hadoop-env.sh file.

• Install required dependencies - OSX: use brew or any other package manager

• Build project and native dependencies with maven

• Copy newly created libraries to the hadoop installation

• Add shell variables either to the ~/.bash_profile, or $HADOOP_INSTALL/etc/hadoop/hadoop-env.sh

Check if native libraries are available:

Hadoop “Unable to load native-hadoop library for your platform” warning (14)

@zhutoulala -- FWIW your links worked for me with Hadoop 2.4.0 with one exception I had to tell maven not to build the javadocs. I also used the patch in the first link for 2.4.0 and it worked fine. Here's the maven command I had to issue

After building this and moving the libraries, don't forget to update hadoop-env.sh :)

Thought this might help someone who ran into the same roadblocks as me

I'm currently configuring hadoop on a server running CentOs. When I run start-dfs.sh or stop-dfs.sh, I get the following error:

WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

I'm running Hadoop 2.2.0.

Doing a search online brought up this link: http://balanceandbreath.blogspot.ca/2013/01/utilnativecodeloader-unable-to-load.html

However, the contents of /native/ directory on hadoop 2.x appear to be different so I am not sure what to do.

I've also added these two environment variables in hadoop-env.sh:

export HADOOP_OPTS='$HADOOP_OPTS -Djava.library.path=/usr/local/hadoop/lib/'

export HADOOP_COMMON_LIB_NATIVE_DIR='/usr/local/hadoop/lib/native/'
