* Removed the apostrophe from the Hadoop user guide menu pull down to be consistent with the crowbar user guide menu item.
* Added raise Errno::ECONNREFUSED, "CM - ERROR: Cannot create CM API resource" on cm-server connection failures in order to force a cm-api retry.
* Only set node[:clouderamanager][:cluster][:cm_api_configured] = true if cm-api executions succeeds. Force this value to false if the cm-server connection fails.

user guide menu pick change + force cm-api retry on cm-server connection failure. [1/1]
* UG & DG updates from Dale. Hopefully the final doc set, but team review still pending.
* Fixed GATEWAY ROLE duplication when HA is deployed (auto deployment mode).
* Fixed the issue with ozzie/hadoop_httpfs init scripts being active
  (CM host inspector - auto deployment mode). Don't use chkconfig --del, use chkconfig
  service off to prevent suceeding service restarts.
* Made the THP regex pattern more specific - match on ^[\t ]* and $ to limit the search
  to line boundaries. Added code to only re-write the THP config files on explicit
  state changes.

Hadoop 2.3.1 - RC #4 [1/1]
* Enhanced CM API integration robustness when the cluster is in a transitional
  deployment state (asynchronous calls for HDFS format, HDFS/MAPR service startup
  and HDFS/MAPR client configuration deployments).
* Changed the CM asynchronous command handler timeout value from 180 seconds
  to 5 minutes.
* Added code to properly handle cases where CM commands are running asynchronously
  in the background and reach immediate execution timeout. Raise an exception for
  these cases in order to force existing retry loop code execution.
* Changed the outer retry loop "retry_count" from 5 attempts to 10 attempts before
  transferring control to the next chef client run.
* Changed the outer retry loop sleep value from 20 seconds to 60 seconds.
* Smoke tested all changes from a clean install and the Hadoop cluster deployed
  successfully on the initial pass.
