> OSIM load under the covers uses Hive to load histogram data into the histogram metadata tables.
> When there is a failure at the Hive level, OSIM reports only:
> *** ERROR[6009] The Optimizer Simulator (OSIM): Error running hive SQL.
> This is not at all helpful in diagnosing the problem.
> We should change OSIM so that it also reports the error information returned from Hive.
