jay vyas commented on HDFS-2551:
--------------------------------

FYI We now have a test in bigtop for this : 
https://issues.apache.org/jira/browse/BIGTOP-1221.   If this gets patched we 
will remove the "sleep" clause.

> fuse-dfs's close() is asynchronous

> FUSE's "release" operation is called asynchronously when a file is closed 
> from userspace. This means that, if a program writes a file, closes it, and 
> immediately re-opens it, it might not succeed. We should figure out some 
> workaround or trick to make close synchronous, if possible.
