Lefty Leverenz commented on HIVE-6847:
--------------------------------------
Doc note: This changes the default value and description for
*hive.exec.scratchdir*, which is already documented in the wiki (in Configuring
Hive as well as Configuration Properties). It also gives a description for
*hive.scratch.dir.permission*, which is not documented in the wiki yet. No
change is made to *hive.downloaded.resources.dir*, it's just removed in one
place and added elsewhere.
Here are all the places in the wiki that *hive.exec.scratchdir* is documented:
* [AdminManual Configuration -- Configuring Hive |
https://cwiki.apache.org/confluence/display/Hive/AdminManual+Configuration#AdminManualConfiguration-ConfiguringHive]
* [AdminManual Configuration -- Temporary Folders |
https://cwiki.apache.org/confluence/display/Hive/AdminManual+Configuration#AdminManualConfiguration-TemporaryFolders]
* [AdminManual Configuration -- Configuration Variables |
https://cwiki.apache.org/confluence/display/Hive/AdminManual+Configuration#AdminManualConfiguration-ConfigurationVariables]
* [Configuration Properties -- hive.exec.scratchdir |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.exec.scratchdir]
* example of using hive.exec.scratchdir (2nd bullet): [Hive CLI -- Examples |

> Currently, the hive server creates scratch directory and changes permission
> to 777 however, this is not great with respect to security. We need to create
> user specific scratch directories instead. Also refer to HIVE-6782 1st
> iteration of the patch for approach.
