Sylvain Lebresne updated CASSANDRA-6612:
----------------------------------------
Attachment: 6612.txt
I do am able to reproduce with the example of the description (which I've
pushed as a dtest).
There is actually two small problem in SecondaryIndexManager. The first one is
in the {{hasIndexFor}} that clearly have a bogus logic when there is more than
one searcher. It's this error that made the code take the wrong path and
trigger the assertion. That said, once fixed, we still have a problem: the
{{search}} is unhappy because we have more than one searcher. And indeed, we've
never supported more than one searcher because even if we have multiple
indexes, we should still have only one searcher for all of them (though we may
have other searcher for custom indexes). That "grouping" of indexes is done by
{{getIndexSearchersForQuery}}. However, that method was grouping using the
class name, which didn't result in all internal index sharing the same searcher
since we have different concrete implementation depending on whether the index
is on a partition key column, clustering key one or regular one. Anyway,
attaching a slightly hackish but simple solution that just make sure we group
all internal indexes properly in {{getIndexSearchersForQuery}} as we should. We
should probably overhaul the {{SecondaryIndexManager}} class at some point
because it's pretty confusing imo but that's not for this ticket.
