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.
