LGTM, go ahead.

nit: missing spaces around '+', and I'd rather just see IllegalStateException() 
there w/ null message - it's not like there can be several reasons for an 
exception here.

All right. I don't like the two indexes though. Can we just get away with a 
'nextCalled' boolean? set it to true in next(), set it back to false in 
remove()?

That, and I'd rather we just threw IllegalStateException with no message, like 
the stdlib iterators do (w/ no need for Preconditions). The last one is a 
nit/taste thing, feel free to ignore.

Mikhail Stepura commented on CASSANDRA-6629:


bq. Wouldn't it be simpler to just alter remove() to return columns.remove(idx 
+ 1) ?

In this case you'll be able to call {{remove}} arbitrary number of times, 
without calling {{next}} at all, which breaks Iterator's contract. 
But yes, that will fix the original problem.

Wouldn't it be simpler to just alter remove() to return columns.remove(idx + 1) 
?

Wow. It seems "nodetool scrub" on node with odd row helped to me. Read repair 
restore that 32-nd row on other replicas, this CQL query worked properly and 
without exception now...

Restoring my original comment 

It looks like {{remove}} at

 should use _idx_ (current item) instead of _idx--_ (next item)

{code:title=Current implementation which throws ArrayIndexOutOfBoundsException}
