             Summary: ombstoneOverwhelmingException is thrown while populating data in recently truncated CF
                 Key: CASSANDRA-6528
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6528
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: Cassadra 2.0.3, Linux, 6 nodes
            Reporter: Nikolai Grigoriev
            Priority: Minor


I am running some performance tests and recently I had to flush the data from one of the tables and repopulate it. I have about 30M rows with a few columns in each, about 5kb per row in in total. In order to repopulate the data I do "truncate <table>" from CQLSH and then relaunch the test. The test simply inserts the data in the table, does not read anything. Shortly after restarting the data generator I see this on one of the nodes:

{code}

I am inserting the data with CL=1.

It seems to be happening every time I do it. But I do not see any errors on the client side and the node seems to continue operating, this is why I think it is not a major issue. Maybe not an issue at all, but the message is logged as ERROR.
