WARN util NativeCodeLoader Unable to load native-hadoop library

Question

When I type hadoop fs -ls in my system, getting this 

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

How to solve this?

Answer 1

To remove this warning, you can use: 

hdfs dfs -ls /

instead of 

hadoop dfs -ls /

The reason you saw that warning is that the native Hadoop library $HADOOP_HOME/lib/native/libhadoop.so.1.0.0 was actually compiled on 32 bit.

Anyway, it's just a warning, and won't impact Hadoop's functionalities.
