[jira] [Created] (HIVE-6727) Table level stats for external tables are set incorrectly

Harish Butani created HIVE-6727:
-----------------------------------

             Summary: Table level stats for external tables are set incorrectly
                 Key: HIVE-6727
                 URL: https://issues.apache.org/jira/browse/HIVE-6727
             Project: Hive
          Issue Type: Bug
            Reporter: Harish Butani


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
