You can run HBase on any size of machine all single node, by default when you start hbase it will store files in /tmp and everything is in 1 JVM. How much data can you jam in there? I'm not totally sure, probably a lot more than you might think, but again limited by the disk. I run it on my mac laptop for example.
I have a patch that will allow a single JVM including zookeeper, but it is locked up in my private git for now. This would get rid of the need to ssh localhost just to start local hbase. -ryan On Fri, Jan 15, 2010 at 1:22 PM, Seth Ladd <sethl...@gmail.com> wrote: > I agree. HBase in a box is essentially MySQL.
