Hardware can still suck. We took a paper bicycle approach to hardware because the real value of Hadoop is in the software.
Crappy hardware is always a burden. It’s the little things. I just want a RAID controller that works without adding special drivers, creating special case installs and going thru obtuse gyrations. Or a Ethernet device that doesn’t require special kernel parameters. I would never ask for both. ^_^
We will persevere, but once it a while, you think it wouldn’t take so much work. :-/
