their problem...tain't true.
I'd appreciate hearing your resul

I have a problem. I installed Hadoop on 2-nodes cluster and run Wordcount

Hi Igor,
I am not sure if Hadoop is designed for realtime requests. I have a feeling
that you are trying to use Hadoop in a way that it isnot designed for. From my
experience, Hadoop cluster will be much slower than "local" hadoop mode when
processing smaller dataset, because there is always ext

But You can change the parameter to reduce the job execution time.
I search an article in Google.
Hope You can find some useful information on that.
