Chris Nauroth commented on HADOOP-8924:
---------------------------------------
Thanks, Matt. I just created HADOOP-9207 to address it separately.

The most important use of the checksum is to enforce the constraint that all
the servers talking to each other be running code compiled from the same source
tree.

Considering this, I think the best solution is to calculate a single global
checksum for the whole project and use the same value across all modules.
That's going to take some restructuring, and I'd prefer to address it in a
separate jira instead of holding up this one.
Alejandro, I think this is all set as long as you are OK with the version 5
patch and my justifications on the tests and release audit warnings. Let me
know what you think.

> Currently, the build process relies on saveVersion.sh to generate
> package-info.java with a version annotation. The sh binary may not be
> available on all developers' machines (e.g. Windows without Cygwin). This
> issue tracks removal of that dependency in Hadoop Common.
