Chris Nauroth commented on HADOOP-12718:
----------------------------------------
[[email protected]], I agree with those suggestions for tightening up the spec
if we keep this patch, but first I have a more fundamental question about
whether or not we keep the patch at all.
Users of the local file system might not always expect the semantics of the
spec and contract tests (as mostly reverse engineered from HDFS). In some
cases, the caller is seeking to emulate HDFS semantics, such as mini-cluster
based tests. In other cases, such as {{LocalDirAllocator}}, a caller
explicitly calls {{FileSystem#getLocal}} and expects to work with the semantics
of the local file system. For example, I mentioned on HADOOP-9507/HADOOP-13082
that there had been a case in the past of Hive expecting very particular
semantics from the local file system.
Unfortunately, aside from full testing of the whole ecosystem, it's hard to
know for sure that this change won't break something, because it's going to
start throwing an exception that users of the local file system hadn't seen
before. This is why I was inclined to revert, at least within the 2.x line.
I'd appreciate your thoughts on whether or not this makes sense or I'm being
overly paranoid. Thanks!
