> This patch aims to fix two issues:
> 1. the original output of nodetool tablehistograms with no tables specified
> is wrong , the output will contains many repeated informations. See the
> picture below.
> The reason is that for
> [tablesList.keys()|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/tools/nodetool/TableHistograms.java#L80]
> will give a Multiset output as tablesList is a Multimap.
> 2. as we have DISCUSS for "Change the useage of nodetool tablehistograms" ,
> for arguments more than two, the output of tablehistograms will be all of the
> tables, it's a bug that we should fix. We can see that the
> [description|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/tools/nodetool/TableHistograms.java#L42]
> of tablehistograms is ,out put the statistic histograms for the given table.
> and the format of the argument is like
