Allen Wittenauer commented on HADOOP-14270:
-------------------------------------------

FWIW, a few bits of history:

* create-release and associated code was never intended by me to end up in 
branch-2.  I don't build or test against branch-2 and haven't in years.  I have 
no idea if the other build changes in trunk that aren't in branch-2 have any 
impact.

* The maven commands and the order of operations in create-release were 
specifically constructed to actually build *everything*.  During 
create-release's development, it was found that various combinations that we 
had documented in various locations left many broken and incomplete HTML pages 
when building the pages for the site.  e.g., jdiff output

* We currently don't link a lot of content that we build, despite a lot of the 
effort put into maintaining it. e.g., jdiff output

* It might be time to actually make three tarballs instead of two:  src, bin, 
docs.  This is a relatively simple thing to do by manipulating the tar command 
lines.

> HADOOP 2.8 Release tar ball size should be smaller

> In voting stage of 2.8.0, [~jojochuang] were reporting that 2.8.0 tar ball 
> are 410 MB while previous release of 2.7.3 is just 205MB. [~andrew.wang] did 
> some advanced investigations that most of added size are from src-html get 
> included in tar.gz which is not necessary in release tar ball.
> I tried to manually build tar ball (using "mvn package -Pdist,native,docs,src 
> -DskipTests -Dtar"), and the dist tar ball is still ~200MB. The only 
> differences is we are using a new dev tool - create-release to create release 
> bits since 2.8 and we should fix from there.
