Hi, A quick update on my attempts to get HBase working.
I have launched successfully clusters with: * standard HBase 0.90.3. I tried it on top of Cloudera Hadoop (the .tar.gz dist), but it should work equally well with other HBase-supported builds. See WHIRR-240 and the new hbase-ec2-090 recipe. * the CDH3u0 linux packages. See WHIRR-334. I also added the ability to set hbase-site.xml properties from the cluster configuration file (see WHIRR-339), similar as to how this is done for Hadoop. If anyone wants to give it a try without going through the trouble of applying the patches, you can get my fork at https://github.com/bdumon/whirr -- Bruno Dumon Outerthought http://outerthought.org/
