…heir names on Windows.
ABFS built list-status entry paths with File.separator, which is a
backslash on Windows. Path("\name:x") then treats "\name" as a URI

with URISyntaxException. The separator here is part of an ABFS/URI
path, not a local filesystem path, so use a forward slash
unconditionally.

only worry about this pr, asking for other branches is a distraction. the backports are just that, backports of whatever is in trunk, and shouldn't be different except where some incompatiblity (like junit) force it. get this one, submit those PRs with a declaration of which azure endpoints you reran the hadoop azure itests against (i.e. |
