Warning: unable to load hadoop native library

0 votes

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

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/"

Any ideas?

Just append word native to your HADOOP_OPTS like this:

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