Igor Novgorodov commented on CASSANDRA-13403:
---------------------------------------------
Bingo!
I've been able to reproduce this in the 5-node cluster. In 3-node test
environment i wasn't able to do it in any way i tried.
After i've added 2 more nodes to fully reflect production cluster environment -
the index immediately broke after repair.
Now i'll try to start with a closest-to-default config as possible to determine
what's the cause...

> I've got table:

> AND compression = {'chunk_length_in_kb': '64', 'class':

> CREATE CUSTOM INDEX bulk_recipients_bulk_id ON cservice.bulks_recipients
> (bulk_id) USING 'org.apache.cassandra.index.sasi.SASIIndex';
> {code}
> There are 11 rows in it:
> {code}
> > select * from bulks_recipients;
> ...
> (11 rows)
> {code}
> Let's query by index (all rows have the same *bulk_id*):
> {code}
> > select * from bulks_recipients where bulk_id =
> > baa94815-e276-4ca4-adda-5b9734e6c4a5;
> >
> ...
> (11 rows)
> {code}
> Ok, everything is fine.
> Now i'm doing *nodetool repair --partitioner-range --job-threads 4 --full* on
> each node in cluster sequentially.
> After it finished:
> {code}
> > select * from bulks_recipients where bulk_id =
> > baa94815-e276-4ca4-adda-5b9734e6c4a5;
> ...
> (2 rows)
> {code}
> Only two rows.
> While the rows are actually there:
> {code}
> > select * from bulks_recipients;
> ...
> (11 rows)
> {code}
> If i issue an incremental repair on a random node, i can get like 7 rows
> after index query.
> Dropping index and recreating it fixes the issue. Is it a bug or am i doing
> the repair the wrong way?
