Mika Ristimaki commented on AVRO-1405:
--------------------------------------
Yeah you are right. If I understood correctly, if fread reads exactly to the
end of file (but doesn't try to read past it) feof() will return false.
In this use case the bug will be triggered if Avro data file is exactly a
multiple of a block size in which that file is read. Most likely LZ4 does some
padding to make the file size always be a multiple of some value. Unfortunately
at least I don't have time to look into this issue now, and also IMO a new Jira
issue should be created for this bug and continue the discussion there.
