Florian Jetter commented on ARROW-1555:
---------------------------------------

[~wesmckinn] Yes, it seems like some abstract methods of the FileSystem class 
(exists, open, etc.)  were not implemented in the wrapper. I'll take care of it

> When writing a arrow table to s3, I get an NotImplemented Exception.
> The root cause is in _ensure_filesystem and can be reproduced as follows:
> import pyarrow
> import pyarrow.parquet as pqa
> import s3fs
> s3 = s3fs.S3FileSystem()
> pqa._ensure_filesystem(s3).exists("anything")
> It appears that the S3FSWrapper that is instantiated in _ensure_filesystem 
> does not expose the exist method of s3.
