Gera Shegalov commented on MAPREDUCE-6400:
------------------------------------------
bq. if inOwner is set to false, we cannot close the wrapped stream when an
exception occurs.
A good pattern is when the stream open API consumer closes the stream. In
IFlileInputStream for shuffle, the stream is opened outside, and therefore
should be and is closed outside.
