Default read_repair_chance value is wrong
-----------------------------------------

                 Key: CASSANDRA-4114
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4114
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 1.0.7
            Reporter: Manoj Kanta Mainali
            Priority: Trivial


The documents says that the default read_repair_chance value is 0.1, and it is 
also declared so in CFMetaDeta. However, when creating a column family with 
"create column family foo" via cli and checking with "show keyspaces" shows 
that the read_repair_chance=1.0. This also happens when creating the column 
family through Hector.

Going through the code, I find that in CfDef class, the constructor without any 
parameters sets the read_repair_chance to 1. Changing this value to 0.1 seems 
to create a column family with the 0.1 read_repair_chance. The best might be to 
remove it from the CfDef as the read_repair_chance is set to the default value 
in CFMetaDeta.
