Sergey Shelukhin commented on HIVE-16671:
-----------------------------------------
The 3-byte check is related to the 3-byte CB header. I dbl checked, we hit
BufferUnderflow (no next byte) on the 3rd get.
I don't think it's related to the file header, that would have happened much
earlier. I may have more details tomorrow about the failure.
> LLAP IO: BufferUnderflowException may happen in very rare(?) cases due to ORC
> end-of-CB estimation
