--------------------------------------
Summary: Prioritize the most under replicated containers for
re-replication
Key: HDDS-12628
URL: https://issues.apache.org/jira/browse/HDDS-12628
Project: Apache Ozone
Issue Type: Improvement
Reporter: Wei-Chiu Chuang
HDDS-6957 implemented the logic to prioritize under replicated containers.
However it does not prioritize those that are minimally replicated and thus in
danger of missing permanently.
As a matter of fact, HDFS implements that logic in LowRedundancyBlocks
[https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/blockmanagement/LowRedundancyBlocks.java]
The same logic could be applicable to Ozone container replication.
