Pete Wyckoff updated HADOOP-3805:
---------------------------------
Attachment: hadoop-3805.txt
I made -obig_writes opt in so it wouldn't cause a backwards compat problem. I
also #ifdef the actual use of the flag because it's only supported in fuse
2.8.0 + and 2.7.4 is the current stable release.
> improve fuse-dfs write performance which is 33% slower than hadoop dfs
> -copyFromLocal

> on hadoop17 running on the namenode/fuse mount point, fuse is 33% slower for
> writing a 1GB file. I don't know right now how to improve this but thought I
> should open up a JIRA for it.
> Note - this benchmark is with no tuning or special fuse config params.
