Using the HCatalog REST API (WebHCat)

...

For example, to specify user.name in a GET :table command:

% curl -s 'http://localhost:50111/templeton/v1/ddl/database/default/table/my_table?user.name=ctdean'

And to specify user.name in a POST :table command:

% curl -s -d user.name=ctdean \
       -d rename=test_table_2 \
       'http://localhost:50111/templeton/v1/ddl/database/default/table/test_table'

...

If the user.name parameter is not supplied when required, the following error will be returned:

{
  "error": "No user found.  Missing user.name parameter."
}

...

Hive log files are described in the Error Logs Hive Logging section of Getting Started.

The original work to add REST APIs to HCatalog was called Templeton. For backward compatibility the name still appears in URLs, log file names, etc. The Templeton name is taken from a character in the award-winning children's novel Charlotte's Web, by E. B. White. The novel's protagonist is a pig named Wilbur. Templeton is a rat who helps Wilbur by running errands and making deliveries as requested by Charlotte while spinning her web.
