I'm a dummy on Ubuntu 16.04, desperately attempting to make Spark work. I've tried to fix my problem using the answers found here on stackoverflow but I couldn't resolve anything. Launching spark with the command ./spark-shell from bin folder I get this message
WARN NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable".
I'm using Java version is
java version "1.8.0_101
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode).
Spark is the latest version: 2.0.1 with Hadoop 2. 7. I've also retried with an older package of Spark, the 1.6.2 with Hadoop 2.4 but I get the same result. I also tried to install Spark on Windows but it seems harder than doing it on Ubuntu.
