Some default values for configuration variables depend on the release number. See webhcat-default.xml for the default values in the Hive release you are using. The file is at http://svn.apache.org/repos/asf/hive/branches/branch-<release_number>/hcatalog/webhcat/svr/src/main/config/webhcat-default.xml in the SVN repository, where <release_number> is Hive release 0.10, 0.11, 0.12, etc. For releases prior to Hive 0.10, WebHCat was in the Apache incubator and its webhcat-default.xml file can be found at ....
Defaults shown here are for the version of WebHCat that is included in Hive release 0.11.0. Defaults for the previous release are shown in the HCatalog 0.5.0 documentation.
