By commodity they do not mean junk room pc's. If you look at the hardware used at yahoo/facebook they typically are beefy systems 8GB ram + fast drives, multi processor.
Regardless of what hardware hadoop is deployed on, it would be great if linux HA can handle restarts. Out of the box hadoop uses shared SSH Keys and a script called start-all stop-all. If a software component on a node goes down no mechanism is in place to automatically restart it. Linux HA seems good for that. The only exception is that hadoop clusters can be big. Linux HA is described as best used on smaller clusters. _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
