      Description

      Pipeline Rule with configurable percentage of pipelines with at least one datanode reported:

      In this rule we consider when at least  90% of pipelines have at least one datanode reported.

       

      This rule satisfies, when we exit chill mode, Ozone clients will have at least one open replica for reads to succeed. (We can increase this threshold default from 90%, if we want to see fewer failures during reads after exit chill mode.
