This looks good to me. Out of curiosity, what made you decide to use
asciidoc rather than the multitude of other options? Cross-platform support
looks good (support for Windows, Mac, and Linux). There also seems to be a
big enough user base for long term supportability.
A few things I noticed:
1.
I don't have geographic location for just the downloads, but here's the
visitors to the site.

Hey Drew,
This could be a very broad question, so I'll give a partial answer and
encourage you to come back for more details.
Impala is a mechanism that sits on top of HBase or HDFS that is design to
filter and process large quantities of data. People generally like Impala
because it supports a s

I tend to agree with Sean, John, and Benson. Option 4 works for now, and
until we can define something that works better (e.g. runtime compatibility
with both hadoop 1 and 2 using reflection and crazy class loaders) we
should not delay the release. Good docs are always helpful where
engineering is
It seems like the ideal option would be to have one binary build that
determines Hadoop version and switches appropriately at runtime. Has anyone
attempted to do this yet, and do we have an enumeration of the places in
Accumulo code where the incompatibilities show up?

Folks,
Sorry to be late to the party, but did we come to a consensus on this?
Seems like we still have opinions both ways as to whether the cpp code
should be packaged with the binary distribution. I would argue that cpp
code is a special case, since the build is so platform dependent. It's

I stand corrected. Thanks for the link, Billie. Looks like we should also
remove the .so file from the -src.tar.gz lest we risk having our project

We still have the option of putting out a separate build for 1.5.0

Seems like it should be easy to add more binary packages that correspond to
the same source release, even after the initial vote.

Folks,
I just fixed a couple of links to the CHANGES files for 1.5.0 and 1.3.6

Thanks for running that checker, Keith. Should we not be worried about the
