Hadoop: Can not start namenode: Unable to load native-hadoop library for your platform

I am trying to run namenode using the following command:

./start-dfs.sh

But I am getting this error. 

05/012/18 11:03:21 WARN util.NativeCodeLoader: Unable to load

Here is my .bashrc file:

export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
export HADOOP_INSTALL=/usr/local/hadoop
export PATH=$PATH:$HADOOP_INSTALL/bin
export PATH=$PATH:$HADOOP_INSTALL/sbin
export HADOOP_MAPRED_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_HOME=$HADOOP_INSTALL
export HADOOP_HDFS_HOME=$HADOOP_INSTALL
export YARN_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_INSTALL/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_INSTALL/lib"

How to solve this?

The entries in your .bashrc file looks fine. Try this, open your etc/hadoop/hadoop-env.sh and replace

export HADOOP_OPTS="$HADOOP_OPTS -Djava.net.preferIPv4Stack=true"

with:

export HADOOP_OPTS="$HADOOP_OPTS -XX:-PrintWarnings -Djava.net.preferIPv4Stack=true"
