Whenever I try running the .jar file on Hadoop, it shows an error:

"Unable to load native-hadoop library for your platform... using builtin-java classes where applicable"

What could be the reason? I'm not able to figure out.

hdfs dfs -cat /outer22/*

outer22 is my output file.

Hadoop include native libraries in the binary distribution for *nix platforms for high performance and the Java version of those libraries for the others.

If your installation is for development, then you could ignore the message. In production could be better use native libraries.
