maxwellguo commented on CASSANDRA-18296:
----------------------------------------
If the options are changed, the way that users use it will change.
For example : nodetool tablehistograms ks1 ks2 , for the old usage means show
the tablehistograms of table : ks1.ks2;
for the new usage means show the tablehistograms of all tables beyond to the
two keyspace : ks1 and ks2;
So I want to know if I can start this work directly now, don't need to pay
attention to other things ,right ？ [~brandon.williams]

> Add some options for nodetool tablehistograms to filter the output
> of System tables and data tables.
> As we know if we nodetool tablehistograms all tables will be output ,but
> system table 's number are too much.
> Add options to filter only output data tables or system tables, together with
> the already exist ks.tb lists, the output options are just fine.
> It seems that tablestats got the -i option that can ignore keyspace, just add
> this first, and then to see wether this can meet our needs
