Lefty Leverenz commented on HIVE-6226:
--------------------------------------

GET version/hive and version/hadoop are documented now and listed in the WebHCat Reference umbrella page, with cross references from the POST hive, mapreduce/streaming, and mapreduce/jar pages:

* [WebHCat Reference | https://cwiki.apache.org/confluence/display/Hive/WebHCat+Reference]
** [GET version/hive | https://cwiki.apache.org/confluence/display/Hive/WebHCat+Reference+VersionHive]
** [GET version/hadoop | https://cwiki.apache.org/confluence/display/Hive/WebHCat+Reference+VersionHadoop]
*** [POST hive | https://cwiki.apache.org/confluence/display/Hive/WebHCat+Reference+Hive]
*** [POST mapreduce/streaming | https://cwiki.apache.org/confluence/display/Hive/WebHCat+Reference+MapReduceStream]
*** [POST mapreduce/jar | https://cwiki.apache.org/confluence/display/Hive/WebHCat+Reference+MapReduceJar]

Please review and correct or improve as needed.

> Calling /version on WebHCat tells the caller the protocol verison, but there is no way to determine the versions of software being run by the applications that WebHCat spawns.  
> I propose to add an end-point: /version/\{module\} where module could be pig, hive, or hadoop.  The response will then be:
> {code}
> {
>   "module" : _module_name_,
>   "version" : _version_string_
> }
> {code}
