He Yongqiang commented on HIVE-1978:
------------------------------------
namit, a .q test file can not include what this jira does. From a .q file, it
is very difficult to know SymlinkTextInputFormat get the input size correctly.
>>getContentSummary' in all existing input formats.
There is no guarantee that the inputformat is from Hive. It is very difficult
to change all input format.
> Hive SymlinkTextInputFormat does not estimate input size correctly
