Andrew Purtell commented on HBASE-11001:
----------------------------------------
bq. Should we check for args[1] also here
We can check for extra sanity, but if we know that args[0] is a String then we
know the command is the original variant. If args[0] is a Hash, then it's the
new variant. Only those two variants are supported.
bq. I would suggest make the *args to args = {}
Show me how to do that and maintain full backwards compatibility with the
current grant command. :-) I rarely touch the shell.

> For testing purposes it would be useful if the shell can support a simple
> syntax for adding cell ACLs to existing cells. Consider a combination of
> current 'grant' and 'scan' commands.

> - { COLUMNS => 'c1', TIMERANGE => [123, 456] }
> - { COLUMNS => ['c1', 'c2'], FILTER => "(PrefixFilter ('foo') AND
> (QualifierFilter (=, 'bar:'))) AND (TimestampsFilter (123, 456))" }
