There are a variety of mechanisms to test your Hadoop installation  - The Installation and Operational Qualification or IOQ is included and installed with your RRE installation.

The Hadoop IOQ scripts are part of a standard installation in the ‘demoScripts’ directory, i.e.

 (from R)    testDir = rxGetOption("demoScriptsDir")

 On Linux with RRE 7.3: 

 /usr/lib64/Revo-7.3/R-3.1.1/lib64/R/library/RevoScaleR

 HadoopIOQ_SetupAndRun.R

HadoopIOQ_Tests.R

Run the scripts.  This may take 30 minutes or more.  When the HTML returns you can review and address any errors.
