Uma Maheswara Rao G commented on HDFS-989:
------------------------------------------

Misread the issue, I was thinking about DFS flush/sync. 
Verified it on local FS. Behaviour for flush and should flush the data. Looks only close is
flushing the data. seems to be a bug. Let me dig into more.
Reopening it.

> They seem to be no-ops. This is really easy to reproduce, just open a file using FileSystem/getLocal(new
Configuration()), write data to the output stream, and then try to flush/sync. I also tried
creating the output stream with a buffer size of 1, but that had no effect.
