> Currently for isolation purposes, many simple java applications run in cluster with 1
map only job. (eg. Oozie). This is not really required with nextgen hadoop (mrv2) and *non-MR*
apps are first class and easy to write.
> A simple hadoop java app can be written which runs in the cluster in the user space.
