Spark Unable to load native-hadoop library for your platform

Question

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.

Answer 1

I think maybe it's the Hadoop library which is compiled for 32bits, while you are on 64bit.

But I would suggest you to fix the following steps, after going through your steps again:

 

• download Hadoop binaries

• unpack to directory of your choice

• set HADOOP_HOME to point to that directory.

• add $HADOOP_HOME/lib/native to LD_LIBRARY_PATH.
