      Description

      Creating a CF in cqlsh -3

      CREATE COLUMNFAMILY ads_config (c_id uuid, ct_id uuid, pt_id uuid, c_type int, creat blob, start timestamp, end timestamp, total int, pending int, PRIMARY KEY ( campaign_id, creat_id, placement_id));
      

      INSERT INTO works fine. SELECT * works fine.

      ALTER TABLE ads_config add cost int;
      

      SELECT * works fine, new field is null.

      ALTER TABLE ads_config drop cost;
      

      Gives a:

      TSocket read 0 bytes
      

      Closing and reopening cql works fine. The column key exists and can't be dropped.

        I was able to reproduce this on 1.1.2, but not in 1.1.3 or any higher version (including the 1.2 trunk). Bisecting says this was fixed by the fix to CASSANDRA-4420, although I'm not sure I can see why.
