Joris Van den Bossche commented on ARROW-13546:
-----------------------------------------------
[~maartenbreddels] sorry, missed this report. Do you still have a reference to
the full traceback? (I don't see it in CI on the PR you mention ..)
I don't fully understand how we didn't catch this or how it's failing. A quick
try to reproduce it:
{code}
In [1]: import fsspec
In [2]: localfs = fsspec.filesystem("file")
In [3]: from pyarrow.fs import PyFileSystem, FSSpecHandler
In [4]: fs = PyFileSystem(FSSpecHandler(localfs))
In [5]: with fs.open_output_stream("test"):
...: pass
...:
{code}
that seems to work fine.
