What Hadoop can, and can't do

So how much hardware are we talking?

Estimates for the hardware needed for Hadoop vary a bit, depending on who you ask. Cloudera's list is detailed and specific on what a typical slave node for Hadoop should be:

· Mid-range processor

· 4 to 32 GB memory

· 1 GbE network connection to each node, with a 10 GbE top-of-rack switch
