HDFS does allow append, so could emulate rewrite-from-x (as needed for append by fastparquet) by truncation followed by open for append.

Apparently not. hdfs3 is not being developed any more, but if you need this, you may want to provide a PR yourself. The low-level function you need is hdfs3.lib.hdfsTruncate.
