Summary: Use of CQD to set scratch directory locations
Key: TRAFODION-2146
URL: https://issues.apache.org/jira/browse/TRAFODION-2146
Project: Apache Trafodion
Issue Type: Improvement
Components: foundation, sql-exe
Reporter: Sandhya Sundaresan
Assignee: Sandhya Sundaresan
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. .
