Subject Re: Usage of data node to run on commodity hardware

Hi Krishna!

I don't see why you couldn't start Hadoop in this configuration.
Performance would obviously be suspect. Maybe by configuring your network
toppology script, you could even improve the performance.

Most mobiles are ARM processor. I know some cool people ran Hadoop v1 on
Raspberry Pis (also ARM), but I don't know if Hadoop's performance
optimized native code has been run successfully on ARM. (Hadoop will use
the native binaries if they are available, otherwise fall back on JAVA
implementations)
