Hadoop "Unable to Load Native-Hadoop Library For Your Platform" Warning

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

I assume you're running Hadoop on 64bit CentOS. The reason you saw that warning is 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.

Here is the way if you do want to eliminate this warning, download the source code of Hadoop and recompile libhadoop.so.1.0.0 on 64bit system, then replace the 32bit one.

Steps on how to recompile source code are included here for Ubuntu:

Good luck.

Java 17 isn't supported - Spark runs on Java 8/11 (source: https://spark.apache.org/docs/latest/).

So install Java 11 and point Spark to that.

The warning unable to load native-hadoop library for platform is quite common and doesn't mean that anything's wrong.
