Date Tue, 01 Aug 2017 23:00:02 GMT

Lei (Eddy) Xu updated HADOOP-14398:
    Attachment: HADOOP-14398.01.patch

Thanks for the detailed review, [~fabbri]!

bq. I think you mean the Filesystem instance; some filesystems don't modify the underlying
FS until close(). 

Good catch. Fixed.

bq. What is the difference in behavior / semantics between opt() and must()?
bq. What is the conflict resolution behavior if there is a builder method (e.g. .someOption())
that conflicts with a Configuration option set via opt() or must()? ("undefined" is a possibility,
but should be specified at least?).

Done. Specified as "undefined" for now. If later on, the specific filesystem builder implementation
needs to revise this, we can file follow on JIRA.

bq. Seems like the invalid settings are:

This is aligned with {{CreateFlag.java}}.
