terasort is the one most people use, as it generates its own datasets.
Otherwise you need a few TB of data and some custom
Hi,
I see there are various posts claiming hadoop is available through official
debian mirrors (for debian squeeze, i.e. stable):

for c++.
but just for experimentation purpose can anybody tell me how to do this .

I'm trying to figure out why, when I use a single input file that is relatively
small (< 3 MB, ~95K records), my Reducer hangs at 33% and the attempt never
completes, with the output below. It looks like there's a problem when it tries
to write to the log file, for some reason it gets Interrupte
Gridmix v3 and TeraSort are good benchmarks to test overall hadoop cluster. But
synthetic load generator is specifically for Namenode. You can refer the
documentation below for how to run this tool.
