  +| *Description*               |	Allows a CQD specification to override the environment variable settings for scatch and temporary file locations, which gives the user more flexibility to change scratch directory locations.
   | *Values*                    |
   Scratch disk locations for overflow (linux path names).
   
  
positive.code: * Specify this location at installation time.
  
  +
  Currently the scratch directory locations are set at installation time. The layer of scratch and temporary file system that manages the scratch file creation and reads the envvar in $TRAF_HOME/etc/ms.env to determine where to create the scratch files.
  
  +
  The CQD will override envvar settings, there are two envvar settings: one is STFS_HDD_LOACTION (default), the other is STFS_SSD_LOCATION (SSD disk).
  
  +
  If the CQD is not set (empty), the envvar setting will work.
  
  +
  The requirement is that the directories MUST exist on every node and Trafodion user will need permission to write to those directories. If not, an error will be returned when a query involving sort/hash overflow is executed.
  
  * Set it in sqconfig.
  
  
negative.code: * If the scratch directory location is not set at installation time, this CQD is valid only for the duration of the session.
  
  +
  These settings will not be stored in $TRAF_HOME/etc/ms.env and will override the environment variables settings as long as the CQD is in effect.
