Addictive Drums Osx Download Yosemite. Introduction This post is to help people to install and run Apache Spark in a computer with window 10 (it may also help for prior versions of Windows or even Linux and Mac OS systems), and want to try out and learn how to interact with the engine without spend too many resources. If you really want to build a serious prototype, I strongly recommend to install one of the virtual machines I mentioned in this post a couple of years ago: or to spend some money in a Hadoop distribution on the cloud. The new version of these VMs come with Spark ready to use. A few words about Apache Spark Apache Spark is making a lot of noise in the IT world as a general engine for large-scale data processing, able to run programs up to 100x faster than Hadoop MapReduce, thanks to its in-memory computing capabilities. It is possible to write Spark applications using Java, Python, Scala and R, and it comes with built-in libraries to work with structure data , graph computation , machine learning and streaming. Spark runs on Hadoop, Mesos, in the cloud or as standalone.
The latest is the case of this post. We are going to install Spark 1.6.0 as standalone in a computer with a 32-bit Windows 10 installation (my very old laptop). Let’s get started. Install or update Java For any application that uses the Java Virtual Machine is always recommended to install the appropriate java version. In this case I just updated my java version as follows: Start –All apps –Java –Check For Updates. Spark Download Feel free also to download the source code and make your own build if you feel comfortable with it.
Extract the files to any location in your drive with enough permissions for your user. Download winutils.exe This was the critical point for me, because I downloaded one version and did not work until I realized that there are 64-bits and 32-bits versions of this file. Here you can find them accordingly: In order to make my trip still longer, I had to install Gitto be able to download the 32-bits winutils.exe. If you know another link where we can found this file you can share it with us.
Decrypt Max Script. (I hope you don’t get stuck in this step) Extract the folder containing the file winutils.exe to any location of your preference. Environment Variables Configuration This is also crucial in order to run some commands without problems using the command prompt. JAVAOPTION: I set this variable to the value showed in the figure below. I was getting Java Heap Memory problems with the default values and this fixed this problem. HADOOPHOME: even when Spark can run without Hadoop, the version I downloaded is prebuilt for Hadoop 2.6 and looks in the code for it.
Download Winutils
To fix this inconvenient I set this variable to the folder containing the winutils.exe file. JAVAHOME: usually you already set this variable when you install java but it is better to verify that exist and is correct. SCALAHOME: the bin folder of the Scala location. If you use the standard location from the installer should be the path in the figure below. SPARKHOME: the bin folder path of where you uncompressed Spark. Post navigation.
