Hey,
I'm new to Hadoop, so please correct me if I'm wrong and bear with me :)
I want to build Hadoop 1.2.1 on my Ubuntu VM.
I'm not able to find the .src.tar.gz file for 1.2.1.
Can anyone help me out?
Thanks,
Vikram Bajaj.
Did you get to look at this?

Question: What are you trying to do here? Are you trying to contribute or
are you trying to learn?

Okay. Thank you!
But, is there any direct file to be downloaded? Versions like 2.7.1 have
the .src.tar.gz file... Has it been removed for 1.2.1?

What version of Apache Hadoop are you running? Recent changes have made
YARN to auto-compute this via hardware detection, by default (rather than
the 8 default).

I doubt there would be any new 1.x hadoop release.
Please take a look at the links James provided.

I was just confused because versions like 2.7.1 have both the .tar.gz file
as well as the .src.tar.gz file, while version 1.2.1 has only the .tar.gz
file.

I'm trying to contribute. But I'm not sure how to. I'm really a beginner
and I clearly need to learn first.
But I'd like to know how to continue what I started.

Apache Hadoop 0.20 and 0.21 are both very old and unmaintained releases at
this point, and may carry some issues unfixed via further releases. Please
consider using a newer release.
Is there a specific reason you intend to use 0.21.0, which came out of a
branch long since abandoned?

It is a two node cluster with one being both master and slave and one

So, now that I have the .tar.gz file, how do I build hadoop?
P.S. : I don't know if this matters, but I've already installed java, ssh,
and set up the namenode. All the nodes (namenkde, secondarynamenode,
datanode) start up successfully and I also ran a mapreduce example that
worked.

Its hadoop 2.5.0.
Whats the logic of default using hardware detection. Say My node has 8
actual core and 32 virtual cores. Its taking 26 as value of vcores
available of this node on RM UI.

Hi Vikram!
Please join the common-dev@hadoop mailing list for these kinds of questions.
Working directly with the source repository is meant for folks working on
contributions in the community, and we define that boundary by joining the
