[dpage · Accepted solution]

if you're reffering to 

" WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable" That's an expected message unless you've setup the native libraries. https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/NativeLibraries.html

Hadoop should still be functional.
