I'm running Hadoop on Ubuntu on a Oracle VM on Windows 7. I'm trying to install Spark on an existing Hadoop installation. For demonstration purposes I do not want to change the existing Hadoop version. Following are the versions of software in my VM.
Ubuntu : 14.04
Java : Java 1.7 and OpenJDK runtime environment (IcedTea 2.5.2)
Hadoop : 2.5.0
I figured out that for Hadoop I need to install Spark 1.6.2. When I try to download Spark 1.6 it doesn't give me the option for Hadoop 2.5 but has options for 2.4 and 2.6. Will Spark 1.6 work on Hadoop 2.4?
I would like to know the appropriate platform requirements for Spark, Scala and Java to install Spark on Hadoop 2.5.
