Anand Avati commented on MAHOUT-1537:
-------------------------------------
I just tried on a Mac and the patch fixes the problem on a mac as well. I don't
have an Ubuntu at hand to check. It might be helpful to try this:
sh$ save=`stty -g`
sh$ mahout spark-shell
....
mahout> :quit
...
sh$ <garbled>
sh$ stty $save # type it in "blind faith" even if invisible
sh$ <OK now>
Does the above manual test work for you, or no?
> minor fixes to spark-shell
