Hi Folks I need to be able to certify that Hadoop works on various operating systems. I do this by running a series it through a series of tests. As I'm sure you can empathize, obtaining all the machines for each test run can sometimes be tricky. It would be easier for me if I can spin up several instances a virtual image of the desired O/S, but to do this, I need to know if there are any risks I'm running using that approach.
Is there any reason why Hadoop might work differently on a virtual O/S as opposed to running on an actual O/S ? Since just about everything is done through the JVM and SSH I don't foresee any issues and I don't believe we're doing anything weird with device drivers or have any kernel module dependencies. Kind regards Steve Watt
