Next Release of Hadoop version number and Kerberos
is the next release of Hadoop going to .21 or .22? I was just wondering,
cause I am hearing conflicting things about the next release having Kerberos
security but looking through some past emails, hearing that it was coming in
.22.

Based on a quick check from Yahoo's github
(http://github.com/yahoo/hadoop-common):
Between yahoo 0.20.10 to yahoo 0.20.104.2:
421 commits
combined diff of 8.75 mb
12 person-years worth of work
consists almost exclusively of security work
For a single person, who doesn't know the code it will take months to
apply it to one of the Apache branches.

The Security/Kerberos support is a huge project that has been in progress
for several months, so the implementation spans tens (if not hundreds?) of
patches. Manually adding these patches to a prior Apache release will take
days if not weeks of work, is my guess.
The 0.20S (aka 0.20.104) branch is over on Yahoo's repository at github.
Currently, the latest Cloudera CDH3 beta release does not have security
integrated, but we are in the midst of this integration as I speak.
Thanks

Ok, that was what I was thinking. would there be a patch that could be
applied to .21 or 20.2 for the Kerberos, since Cloudera is touting there
.20S version, but my preference is staying with the latest apache distro
and patch as needed
Just curious

Hi Ananth,
The next release of Hadoop will be 0.21.0, but it won't have Kerberos
authentication in it (since it's not all in trunk yet). The 0.22.0
release later this year will have a working version of security in it.
Cheers,
Tom
