I think it's safer to use a newer version (0.94): there are a lot of things around performances & volumes in the 0.92 & 0.94. As well, there are much more bug fixes releases on the 0.94.
For the number of region, there is no maximum written in stone. Having too many regions will essentially impact the performances. As I said, having 60TB of data per machine is not standard today (points are: that's a lot of disk a single machine; what's the impact if you lose a node; what will be the network load, ...). I suppose all this is documented in the usual books on HBase. On Mon, Dec 17, 2012 at 11:26 AM, tgh <guanhua.t...@ia.ac.cn> wrote: > number of region for ONE server?
