> When doing "fs -put" to a WebHdfsFileSystem (webhdfs://), the FsShell goes OOM if the file size is large. When I tested, 20MB files were fine, but 200MB didn't work.
> I also tried reading a large file by issuing "-cat" and piping to a slow sink in order to force buffering. The read path didn't have this problem. The memory consumption stayed the same regardless of progress.
