URL: https://github.com/apache/hadoop/pull/6904#issuecomment-2213633311
Raising an java.io.EOFException when passing down an offset/range > file
length is what is required, so all is good.
s3a and abfs support the openFileWithOptions so they can save a HEAD request
if they know the file length/file status of the file. I'd recommend
implementing the interface because it can be used to speed up file opening.
Adoption has been slow as apps still try to build with older hadoop releases,
which is why #6686 is making it easier to use reflection to invoke them...I
have a matching change in parquet which will take the known file status and
save some IO.
