> This Jira is to implement one of the chill mode rule.
> h2. Pipeline Rule with configurable percentage of open pipelines with all datanodes reported:
> h2. In this rule, we consider when at least 10% of the pipelines have all 3 data node's reported (if it is a 3 node ratis ring), and one node reported if it is a one node ratis ring. (The percentage is configurable via ozone configuration parameter).
>  
> This rule satisfies, once the SCM is restarted, and after exiting chill mode, we have enough pipelines to give for clients for writes to succeed.
