Raghu Angadi commented on HADOOP-3175:
--------------------------------------
bq. I don't see why rest (ex. '> /dev/null')
"> /dev/null" is not part of the command. That is interpreted by the user
shell. I don't think there is a requirement that "-" should only be the last
arg. Could also add test case where it is not the last arg to your test?
Would replacing {noformat}if (args[pos].charAt(0) == '-') ... {noformat} with
{noformat} if (args[pos].charAt(0) == '-' && arg[pos].length > 0) ...
{noformat} be enough for the fix?
> "-get file -" does not work
