Description

Temp tables that are analyzed by the SemanticAnalyzer get their default location set to a location in the session directory. Export of Acid tables also creates temp tables, but this is done via a plan transformation, and the temp table creation never goes through the SemanticAnalyzer, meaning the location is not set. There is some other logic in DDLTask (which I am changing in HIV-19837) which ends up automatically setting this path to the default table location in the warehouse directory. This should be fixed so that the path defaults to a location in the session directory, like with normal temp tables.
