Bruno Dumon commented on WHIRR-240:
-----------------------------------

Indeed, we need a recipe, something like "hbase-ec2-090.properties". Should be 
trivial to make, but maybe someone else can double-check this patch (I had 
trouble testing it on ec2 yesterday, cfr. the boostrap phase timeout problems).

Since there was some discussion on the users list as to whether this 
jar-replacing is a good approach, I'd like to throw in my arguments for adding 
this:

 * most importantly, HBase users currently looking into Whirr will be 
disappointed as they can't run any recent version

 * from Andrew's comment, I take that even with HBase 0.92, people might want 
to run different Hadoop versions (e.g. CDH), which will likely still require 
replacing the hadoop-core jar in HBase, for example because of differences in 
the RPC protocol.

Besides this, it is 'the' approach in HBase land, cfr 
http://hbase.apache.org/book/hadoop.html: 'Replace the hadoop jar found in the 
HBase lib directory with the hadoop jar you are running on your cluster to 
avoid version mismatch issues'.

> HBase 0.90.0 is a difficult release as it either needs CDH or a patched 
> Hadoop (with append) to work. The Apache tarballs won't do and HBase will not 
> start. 
> One way possible is to deploy the Apache Hadoop 0.20.2 tarball and then 
> override the core jar with the one supplied by HBase. Since HBase relies on 
> Hadoop to be setup by the Whirr service we would need some surgery that would 
> imply service ordering.
