Description

https://github.com/dask/adlfs/issues/171

I am unable to save data to Azure Blob using ds.write_dataset() with pyarrow 3.0 and adlfs 0.6.0. Reverting to 0.5.9 fixes the issue, but I am not sure what the cause is - posting this here in case there were filesystem changes in pyarrow recently which are incompatible with changes made in adlfs.
