Uninterruptible power supply (UPS) in a Hadoop based cluster

I was wondering about the possibility/need of including an uninterruptible power supply (UPS) in a Hadoop based cluster, and if its use is globally accepted or not. I'm sorry if the question is so obvious, but I don't seem to find any related info in the web. The idea is to build a small (one rack) cluster for experimentation purposes.

Thank you in advance!

Re: Uninterruptible power supply (UPS) in a Hadoop based cluster

If you want to mitigage the chance of loosing data it is deffinitly recomended. The problem is does the cost justify the risk. You would need a UPS big enough to give you time to shutdown all the hosts. 

 

I recomend a customer have UPS capacity for all servers. You are spending the mony to have a Enterprise Grade piece of hardware so you should be putting it on Enterprise Grade Power.
