-----------------------------------
Summary: Python LocalFileSystem directory-creation semantics
Key: BEAM-4747
URL: https://issues.apache.org/jira/browse/BEAM-4747
Project: Beam
Issue Type: Improvement
Components: sdk-py-core
Affects Versions: 2.5.0
Reporter: Ryan Williams
Assignee: Ryan Williams
Coming out of discussion on
[BEAM-4742|https://issues.apache.org/jira/browse/BEAM-4742] /
[#5903|https://github.com/apache/beam/pull/5903] is a question of whether
{{LocalFileSystem.{open,create,copy,rename}}} should create
intermediate (destination) directories, or fail with {{IOError}}'s (as the
stdlib {{os}} module generally will).
If the semantics of {{LocalFileSystem}} should mimic those of distributed
filesystems (in the spirit of [recent discussion about {{DirectRunner}} being
more like a local simulation of a distributed runner than a production-grade
local runner|https://www.mail-archive.com/dev@beam.apache.org/msg08410.html]),
then this makes sense, and it sounds like [~lcwik] and [~angoenka] are in favor
of this interpretation.
I'll repurpose [#5903|https://github.com/apache/beam/pull/5903] to this end
unless I hear otherwise.
