Pete Wyckoff updated HADOOP-3485:
---------------------------------
Release Note:
Write support added, but performance of writes not looked at yet.
I also changed the unit tests to be callable from the top level hadoop build
file
Note that on Linux, writes require kernel 2.6.15 or above
was:

> Doesn't support writes because fuse protocol first creates the file then
> closes it and re-opens it to start writing to it. So, (until hadoop-1700), we
> need a work around.
> One way to do this is to open the file with overwrite flag on the second
> open. For security, would only want to do this for zero length files (could
> even check the creation ts too, but because of clock skew, that may be
> harder).

> ps since mostly already implemented, this should be a very quick patch
