Aditya Shah updated HIVE-17404:
-------------------------------
Attachment: HIVE-17404.patch
Target Version/s: (was: 3.0.0, 2.4.0)
Status: Patch Available (was: Open)
Have submitted a patch which Adds a check for ORC bytes in Orctail before
putting it in the local cache. This issue was faced because in HIVE-16133 we
minimize the tail data stored in the cache. This cause a call to extractTails
which rebuilds the OrcTail while using it. This further causes a check for
footer and results in an error being thrown. Because for old orc files when the
tail is not present we check the head for the “ORC” text, but in the case where
we just have a tail as in this call, it causes an exception.

> 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
