             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: Linux 2.6.32-431.20.3.el6.x86_64 #1 SMP Thu Jun 19 21:14:45 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

I traced simple 'create table' command and found that cassandra calls many times "SELECT * FROM system.schema_columns" and "SELECT * FROM system.schema_triggers". In my tracing log it is 132 and 66 times. I'm not sure if it is tracing issue or 'create table' issue, but the result is weird.
