Sylvain Lebresne resolved CASSANDRA-2719.
-----------------------------------------
Resolution: Duplicate
Fix Version/s: 0.8.0
This turns out to be a duplicate of CASSANDRA-2675. I've thus committed it to
0.8.0 too (it was already committed on the 0.7 and 0.8 branches).
> Super Column Counters Increment on Read
> ---------------------------------------
>
> Key: CASSANDRA-2719
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2719
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 0.8 beta 1
> Environment: Tested on 0.8.0-rc1 on both a 3 node cluster and single
> instance.
> Reporter: Greg Hinkle
> Fix For: 0.8.0
>
> Attachments: SuperCountTest.java
>
>
> Running a large number of batch increments on a set of counters in a super CF
> seems to put some of the counters into a strange state where they increment
> every time you read from them. Including just doing a list or get from the
> cli. Will attach test that reproduces problem.
> For example, after running the test (and it completing and the process
> stopping).
> [default@Chires] get CountTest[01];
> => (super_column=1306512590369,
> (counter=n, value=25625))
> Returned 1 results.
> [default@Chires] get CountTest[01];
> => (super_column=1306512590369,
> (counter=n, value=26610))
> Returned 1 results.
