Cristina L. Abad commented on HDFS-4869:
----------------------------------------
Prior to the refactoring of FsShell (HADOOP-7176), the get command supported
the use of "-" to download a file and write its contents to stdout. For
example, see HADOOP-3175. Currently, this can be worked around by using -cat
instead of -get. However, for consistency, both put and get should support "-"
in place of stdin or stdout, respectively.
> FsShell get command does not support writing to stdout
