Warning Unable to load Hadoop Native Library for your platform [closed]

Question

I am a CentOS user and am running Hadoop Framework on it.

I have started the DFS through start-all.sh command and I found this error popping up

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

The /native/directory/ on Hadoop 2.x is different so am confused a bit.

I have also edited the Hadoop-env.sh file

export HADOOP_OPTS="$HADOOP_OPTS -Djava.library.path=/usr/local/hadoop/lib/"
export HADOOP_COMMON_LIB_NATIVE_DIR="/usr/local/hadoop/lib/native/"

Can anyone help me resolve this issue?

Answer 1

 I had the same issue. It's solved by adding the following lines in .bashrc:

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

Hope this Helps
