Elek, Marton updated HDDS-1178:
-------------------------------
Description:
This Jira is to implement one of the chill mode rule.
*Pipeline Rule with configurable percentage of open pipelines with all
datanodes reported*: 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.
