Hi, For early stages of new development, an all-localhost setup is enough for basic testing.
However to test with any appreciable data size or load, indeed you need to think 5-10 servers. I use on demand clusters of ~5 nodes on EC2 for development and for functional testing of new changes. See http://github.com/apurtell/hbase-ec2 If you want accurate performance measurements, then EC2 won't do, it must be real hardware, perhaps rented (Softlayer, Serverbeach, Rackspace, etc.) - Andy > From: hbase...@aol.com <hbase...@aol.com> > Subject: Contributing to hbase but test with less hardware > To: user@hbase.apache.org > Date: Tuesday, October 26, 2010, 3:00 PM > > Dear HBase devs, > > > I am reading the HBase sources and have also read the > http://wiki.apache.org/hadoop/Hbase/HowToContribute > wiki page including the jira "noob" label suggestion.
