    Hadoop on VMware vs Physical

    Does anyone have any good reasons for or against deploying Hadoop on virtual machines vs physical. Looking for justification for going physical other than 'everyone else does it'
    Politicians are wonderfull people, as long as they stay away from things they don't understand, like working for a living!

    Isn't the reason for physical the age old one that its just gives you that additional x% of performance.

    Personally I really don't see the point. Its just easier to keep everything virtual...
    merely at clientco for the entertainment

      I can tell you that GPFS doesn't work well on a virtualised environment, so I suspect the less mature HDFS won't either.

        I'll (maybe) let you know on Friday as this is exactly my task for the coming week.
        -Maybe have to take it into general if it goes badly......

          A direct 1 to 1 mapping on vmware to physical host? Otherwise isn't having extra real cores kind of the whole point?

            That tells you why you should vitrualise - so just prove the reverse.

              Answers my question. Although I suspect it depends on the nature of the problem you're solving on Hadoop.
