    That's right - basic string comparison - will fix it :)

> Allow a CQD specification to override the env settings for STFS locations.
> Currently the scratch directory locations and set at installtion time . The 
> STFS layer that manages the scratch file creation reads the envvar in ms.env 
> to determine where to create the scratch files.
> Now we allow a CQD to be specified that will override the envvar setting. If 
> the CQD is not set (empty) , the envvar setting will work. This will give the 
> user some flexibility to change scratch directory locations. The requirement 
> is that the directoryies MUST exists on every node and that Trafodion user 
> will need permissions to write to those directories. If not an error will be 
> returned when a query invliving sort/hash overflow is executed. .
