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

Question

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:

Answer 1

Move your compiled native library files to $HADOOP_HOME/lib folder.

Then set your environment variables by editing .bashrc file

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

Make sure your compiled native library files are in $HADOOP_HOME/lib folder.

it should work.
