Support 'rb+' mode for open by truncation #134

Open martindurant opened 7 years ago

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

Hello, The function completed?

martindurant commented 5 years ago

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.
