Check to see if Impala has the necessary permissions to access the source and dest paths for this LOAD statement (which maps onto a sequence of file move operations, with the requisite permission requirements), and check to see if all files to be moved are in format that Impala understands. Errors are raised as AnalysisExceptions.
