Summary: Healthy pipeline Chill Mode
Key: HDDS-1178
URL: https://issues.apache.org/jira/browse/HDDS-1178
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Bharat Viswanadham
Assignee: Bharat Viswanadham
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.
