Thanks Rob,
There is one thing bothers me.
I have complex row key.
$ create table b (x int, s text, ((x,s)) primary key);
In cqlsh I cannot fill row key partially:
$ insert into b (x) values(4);
Bad Request: Missing mandatory PRIMARY KEY part s
But nodetool can find hosts by incomplete key
$ nodetool -h cas3 getendpoints anti_portal b 12
192.168.4.4
192.168.4.5
192.168.4.6
I found that columns are separated by ":".
And If I pass to many elements then the error happens.
$ nodetool -h cas3 getendpoints anit_portal b 12:dd:dd
Exception in thread "main"
