1.0 is a rename of the 0.20 line, its not > 0.21+. Other branches will be renamed eventually, but the rename has not happened yet. Agree its confusing, but perhaps the illustrations on http://www.cloudera.com/blog/2012/01/an-update-on-apache-hadoop-1-0/ and https://blogs.apache.org/bigtop/entry/all_you_wanted_to_know will help you understand completely. >> The page at http://wiki.apache.org/hadoop/HowToContribute goes over >> setting up the trunk development workspace and should help you get >> started. >> >> What do you mean by "most stable"?

Its a chaotic series of numbers after the rename happened partially, but the numbering will stabilize soon. Also, best to ask CDH specific questions over its active user forums at https://groups.google.com/a/cloudera.org/group/cdh-user/topics >> > For hadoop common repo, which version should I use for a particular hdfs >> > version? >> >> Don't quite get this question. >> > Because common repo and hdfs repo is separate, is it possible to have some > incompatibility between the two. The project was all merged back recently, you only need to use the hadoop-common repository: i.e. Use http://svn.apache.org/repos/asf/hadoop/common/trunk/ (or) https://github.com/apache/hadoop-common / http://git.apache.org/hadoop-common.git -- Harsh J Customer Ops.
