----------------------------------------

             Summary: Secondary Index Sporadically Doesn't Return Rows
                 Key: CASSANDRA-4785
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4785
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.1.5
         Environment: Ubuntu 10.04
Java 6 Sun
Cassandra 1.1.5 upgraded from 1.1.2 -> 1.1.3 -> 1.1.5
            Reporter: Arya Goudarzi


I have a ColumnFamily with caching = ALL. I have 2 secondary indexes on it. I have noticed
if I query using the secondary index in the where clause, sometimes I get the results and
sometimes I don't. Until 2 weeks ago, the caching option on this CF was set to NONE. So, I
suspect something happened in secondary index caching scheme. 

Here are things I tried:

1. I rebuild indexes for that CF on all nodes;
2. I set the caching to KEYS_ONLY and rebuild the index again;
3. I set the caching to NONE and rebuild the index again;

None of the above helped. I suppose the caching still exists as this behavior looks like cache
mistmatch.

I did a bit research, and found CASSANDRA-4197 that could be related.

Please advice.
