  You need to consider how soon the maximum number of rows are materialized on the Region Servers.  When filtering is pushed down to Region Servers,
  then it can take a longer time depending upon the query and the predicates involved. This can result in HBase scanner timeouts. 
  | *Production Usage*          | Use the default setting and reduce the value to avoid HBase scanner timeouts. Please contact {project-support}.
  if you think that you need to use this CQD.

  | *Description*               |	Allows a CQD specification to override the env settings for STFS locations.
  | *Values*                    | Scratch disk locations for overflow (linux path names).
  | *Usage*                     | Currently the scratch directory locations are set at installation time. The STFS layer that manages the scratch file creation reads the envvar in ms.env to determine where to create the scratch files.
  
  The CQD is allowed to be specified that will override the envvar setting. This will give the user some flexibility to change scratch directory locations.
  
  If the CQD is not set (empty), the envvar setting will work.
  
  The requirement is that the directories MUST exists on every node and Trafodion user will need permissions to write to those directories. If not, an error will be returned when a query involving sort/hash overflow is executed.
  
  | *Production Usage*          | Please contact {project-support}.
  | *Impact*                    | More volume of data can be processed, for example, large data set.
  | *Level*                     | System.
