The virtual image assumes you have a 64bit computer and one of the popular virtualization environments. Sqoop is a highly parallelized utility. Can these technologies play together?. CFR - another java decompiler.

CFR will decompile modern Java features - up to and including much of Java 9, but is written entirely in Java 6, so will work anywhere!() - It'll even make a decent go of turning class files from other JVM langauges back into javaTo use, simply run the specific version jar, with the class name(s) you want to decompile (either as a path to a class file.

There is a lot of excitement about Big Data and a lot of confusion to go with it. This article provides a working definition of Big Data and then works through a series of examples so you can have a first-hand understanding of some of the capabilities of Hadoop, the leading open source technology in the Big Data domain.
