Namit Jain commented on HIVE-2996:
----------------------------------

@Carl, facebook is pretty close to deploying the trunk, which has its own 
advantages and disadvantages.
The deployment framework at facebook is slightly different (maybe) from others 
- so, the first step is to 
have the ability to create the environment in open source. This includes having 
all the hooks that we have used, 
and the hive-site.xml.

The high level goals of HIVE-2670 and this are similar, but the major 
difference is the hooks, hive-site.xml etc.
Once this is done, I also plan to have a script which can be run (via jenkins) 
automatically, assuming the users
have a mysql db. and HADOOP_HOME installed. This way, for a new commit, 
Facebook will be pretty confident that it
is not breaking anything. Also, it allows outside Facebook contributors to 
debug the problems we encounter. In absence
of this environment, we (inside Faceook) end up debugging all these issues.

For the first cut, it need not even be integrated with ant - but, that would be 
good to do eventually.
Also, I am not planning performance regressions initially, but again that would 
be good to have.
