------------------------------------------
Hi Nathan, Even though we fix the above problem, we can not flush the bytes
less than LOCAL_FS_BYTES_PER_CHECKSUM_KEY. Because LocalFileSystem is checksum
file system. by default the value is 512 bytes. It maintains the data in
internal buffers till then.
Thanks
Uma

> 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.
