Steve Loughran commented on HADOOP-13714:
-----------------------------------------
assume things like {{hadoop fs -ls hfds://nn1:/temp}} will be parsed through
some shell script, even if just grep and awk
This is where windows PowerShell is actually slick: you can chain together more
than just text and expect piped things to work.
