Prasanth Jayachandran updated HIVE-17404:
-----------------------------------------
Description:
Some old files do not have Orc FileTail. If file tail does not exist, split
generation should fallback to old way of storing footers.
This can result in exceptions like below
{code}
ORC split generation failed with exception: Malformed ORC file. Invalid
