-------------------------------
Hi, [~ashutoshc]
The current test cases in Hive already cover this case but the result is wrong.
HIVE-6727.3.patch fixes the output file of the case.
Thank you for your review.

> 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
