> if you do the following:
> {code}
> CREATE EXTERNAL TABLE anaylyze_external (a INT) LOCATION 'data/files/ext_test';
> describe formatted anaylyze_external;
> {code}
> The table level stats are:
> {noformat}
> Table Parameters:
> 	COLUMN_STATS_ACCURATE	true
> 	EXTERNAL            	TRUE
> 	numFiles            	0
> 	numRows             	6
> 	rawDataSize         	6
> 	totalSize           	0
> {noformat}
> numFiles and totalSize is always 0.
> Issue is:
> MetaStoreUtils:updateUnpartitionedTableStatsFast attempts to set table level stats from FileStatus. But it doesn't account for External tables, it always calls Warehouse.getFileStatusesForUnpartitionedTable
