Daniel Strawson commented on CASSANDRA-4973:
--------------------------------------------
ok - I've just done the following:
1. run the query "get region where countryCode=GB". This returned 13 rows OK.
2. stopped and started cassandra (kill pid).
3. ran the same query. This returned no rows.
At this point there are no errors in the log file -
Next I'm doing the following:
4. run update column family region with column_metadata=[];
5. run update column family region with column_metadata=[ ...] ; (see original
schema above)
6. ran the same query, it returned 13 rows OK.
here is the log file from the point where the restart happened:

> Secondary Index stops returning rows
> ------------------------------------
>
> Key: CASSANDRA-4973
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4973
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.1.2, 1.1.6
> Environment: Centos 6.3, Java 1.6.0_35, cass. 1.1.2 upgraded to 1.1.6
> Reporter: Daniel Strawson
>
> I've been using cassandra on a project for a little while in development and
> have recently suddenly started having an issue where the secondary index
> stops working, this is happening on my new production system, we are not yet
> live. Things work ok one moment, then suddenly queries to the cf through
> the secondary index stop returning data. I've seen it happen on 3 CFs. I've
> tried:
> - various nodetools repair / scrub / rebuild_indexes options, none seem to
> make a difference.
> - Doing a 'update column family <whatever> with column_metadata=[]' then
> repeating with my correct column_metadata definition. This seems to fix the
> problem (temporarily) until it comes back.
> The last time it happened I had just restarted cassandra, so it could be that
> which is causing the issue, I've got the production system ok at the moment,
> I will try restarting a bit later when its not being used and if I can get
> the issue to reoccur I will add more information.
> The problem first manifested itself in 1.1.2, so I upgraded to 1.1.6, this
> has not fixed it.
> Here is an example of the create column family I'm using for one of the CFs
> that affected:
> create column family region
> with column_type = 'Standard'
> and comparator = 'UTF8Type'
> and default_validation_class = 'BytesType'
> and key_validation_class = 'UTF8Type'
> and read_repair_chance = 0.1
> and dclocal_read_repair_chance = 0.0
> and gc_grace = 864000
> and min_compaction_threshold = 4
> and max_compaction_threshold = 32
> and replicate_on_write = true
> and compaction_strategy =
> 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy'
> and caching = 'KEYS_ONLY'
> and column_metadata = [
>
> {column_name : 'label',
> validation_class : UTF8Type},
>
> {column_name : 'countryCode',
> validation_class : UTF8Type,
> index_name : 'region_countryCode_idx',
> index_type : 0},
>
> ]
> and compression_options = {'sstable_compression' :
> 'org.apache.cassandra.io.compress.SnappyCompressor'};
> I've noticed that CASSANDRA-4785 looks similar, in my case once the system
> has the problem, it doesn't go away until I fix it.
