update KEYS file instructions

  = Preparation =
  
          1. Bulk update Jira to unassign from this release all issues that are open non-blockers and send follow-up notification to the developer list that this was done.
+ 	1. If you have not already done so, [[http://www.apache.org/dev/release-signing.html#keys-policy|append your code signing key]] to the [[https://dist.apache.org/repos/dist/release/hadoop/common/KEYS|KEYS]] file on the website. Also [[http://www.apache.org/dev/release-signing.html#keys-policy|upload your key to a public key server]] if you haven't. End users use the KEYS file (along with the [[http://www.apache.org/dev/release-signing.html#web-of-trust|web of trust]]) to validate that releases were done by an Apache committer. Once you commit your changes, log into {{{people.apache.org}}} and pull updates to {{{/www/www.apache.org/dist/hadoop/core}}}. For more details on signing releases, see [[http://www.apache.org/dev/release-signing.html|Signing Releases]] and [[http://www.apache.org/dev/mirror-step-by-step.html?Step-By-Step|Step-By-Step Guide to Mirroring Releases]].
- 	1. If you have not already done so, update your @apache.org account via [[http://id.apache.org/|id.apache.org]] with your key; also add and commit your public key to the Hadoop repository [[http://svn.apache.org/repos/asf/hadoop/common/dist/KEYS|KEYS]], appending the output of the following commands:{{{
- gpg --armor --fingerprint --list-sigs <keyid>
- gpg --armor --export <keyid>
- }}} and publish your key at [[http://pgp.mit.edu/]]. Once you commit your changes, log into {{{people.apache.org}}} and pull updates to {{{/www/www.apache.org/dist/hadoop/core}}}.
