Subject Re: [ANNOUNCE] Intend to build a 0.20.205.1 candidate next Friday 11 Nov.
Date Fri, 11 Nov 2011 18:34:09 GMT
Hey Matt,

My understanding of introducing the new 4 part version scheme was to
provide stability. Eg if someone is running 0.20.205.0 wants to be
able to get just critical bug fixes (maybe they don't even use HBase)
to what they're running then they can use 205.1, .2 etc. If someone
running 205 wants something that's more than a critical bug fix (eg a
performance optimization like HDFS-2246) then they upgrade to the next
minor version (206), which still supports a path for people running
205. This allows us to serve both users (those who want just critical
bug fixes to what they're running and those who want stuff like perf
improvements for HBase), while the plan of putting everything in the
point release serves one type of user at the expense of the other.
What's the disadvantage of putting this in 206? That can be released
soon as well right? According to the wiki it was supposed to branch
last month.

Thanks,
Eli
