Hadoop 0.19.2 Contrib DataJoin

[Alex Parvulescu <al...@gmail.com>]

Hello,

I am using Hadoop 0.19.2 and DataJoin (contrib/datajoin), and I'd like to
know if this is still maintained by anyone, of if there is a wiki page or
something where I could get more info.
I was looking at Hadoop 0.21 release and it seems that this part of the code
did not change.

I'd like to know if I can submit a for this small project. It's nothing
much, I just added some generics. It's not perfect, but I think it's a good
start.

Can you please let me know what you think, and point me into the right
direction.

thanks,
alex

NP.  Best place to start is probably by reading this:

http://wiki.apache.org/hadoop/HowToContribute

That will answer a lot of your basic questions, I suspect.

0.19 is basically dead.  You can always submit a patch for a branch, but it
likely won't mean much.  Patches are generally done towards trunk.

There is a whole mailing list that sends out jira information.  Folks who
read that, if they are interested, will follow it that way or via watches on
the jira itself.

Good luck!

Hello Allen,

Thanks for your reply!
Can you tell me where should I start?

Should I use hadoop/common/branches/branch-0.19 or
hadoop/common/tags/release-0.19.2 as a reference for the patch?

Then I submit this patch as an improvement in JIRA under Hadoop Map /Reduce
so somebody can take a look and tell me if it ok? Or should I just post it
here?

thanks,
alex

You can always submit a patch.  Getting it committed is usually a much
harder task.  If it is something that few/any of the committers use, it will
usually require significant hand waving to get it in.  [This will likely
count towards that hand waving, so go for it. :) ]
