Brian Bockelman updated HDFS-860:
---------------------------------
Attachment: HDFS-860.patch
Attaching a simple patch to get around this problem - silently suppress the
error if you call truncate with non-zero size.
This patch should be considered carefully; for our local community, the benefit
(scp can be used to copy files onto a remote HDFS mount) outweighs the cost
(breaking error codes for the truncate call).
I primarily wanted to get this issue and patch documented for others to
potentially use (and to make sure it has proper licensing :)

> For whatever reason, scp issues a "truncate" once it's written a file to
> truncate the file to the # of bytes it has written (i.e., if a file is X
> bytes, it calls truncate(X)).
> This fails on the current fuse-dfs.
