Yeah, our version story is a little messy at the moment. Would appreciate any input that would help us make it more clear.

The branch-0.20-append link in the documentation is to the branch in SVN that you'd need to checkout and build. This was not obvious to you so I need to reword this paragraph to be more clear. How about if I insert after the above sentence "Checkout this branch [with a link to the branch in svn] and then compile it by..."

What would you suggest? > Question: does cloudera hadoop version (0.20.2) is suitable for hbase > 0.90.1? CDH3b2,CDH3b3, or CDH3b4 are all suitable (each is an hadoop 0.20.2++). > In case I am going to use cloudera do I need to install all parts (hadoop, > hbase ,zookeper ...) from cloudera or it is possible to take only hadoop > installation and other products (hbase , zookeper) I can install from > standard distributions? > Any of above combinations should work. If you use CDH3b4, you can take all from CDH since it includes 0.90.1. Otherwise, you could use CDH hadoop and use your hbase build for the rest. St.Ack
