[jira] [Created] (CASSANDRA-3169) read repair: NEWS does not match actual behavior

read repair: NEWS does not match actual behavior
------------------------------------------------

                 Key: CASSANDRA-3169
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3169
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.0
            Reporter: Jonathan Ellis
            Assignee: Jonathan Ellis
            Priority: Minor
             Fix For: 1.0


NEWS says:

{noformat}
    - Hinted Handoff is substantially more robust, with the result that
      when HH is enabled, repair only needs to be run if a node crashes.
    - Because of this, read repair is disabled now by default on newly
      created ColumnFamilies.
{noformat}

But default RR value is still 1.0.

Jonathan Ellis commented on CASSANDRA-3169:
-------------------------------------------

Patch reduces default RR to 0.1 and updates NEWS to match -- seems premature to default it to all the way off.
