Accessing Table Information with REST

Table information can be retrieved from any host that has HTTP access to the host where the WebHCat server is running. A Web browser or an HTTP client such as curl or wget can be used to verify the functionality.

The base URL for REST access to table information is http://<SERVERHOST>:50111/templeton/v1/ddl.

Examples of specific URLs:

http://<SERVERHOST>:50111/templeton/v1/ddl/database/?user.name=hive
http://<SERVERHOST>:50111/templeton/v1/ddl/database/default/table/?user.name=hive
http://<SERVERHOST>:50111/templeton/v1/ddl/database/default/table/groups?user.name=hive

Example output:

{"columns":[{"name":"name","type":"string"},{"name":"placeholder","type":"string"},{"name":"id","type":"int"}],"database":"default","table":"grouptable"}
