>             Project: Hadoop Distributed Data Store
>          Issue Type: Bug
>          Components: SCM
>            Reporter: Bharat Viswanadham

> Condition for to Start Replication monitor thread.
>  # Exit Chill mode
>  # Time out (configurable value) default to 5 minutes. Additional time out is added to
give some additional time for datanodes to report and make pipelines healthy.
> So, once we are out of chillmode, we fire ChillModeStatus, this ReplicationTimer Class
will listen to that event, and wait for a configurable time, and then emit replicationEnabled.
> The current code, when we are out of chill mode, we set replication enabled.
