avijayanhwx opened a new pull request #2874:
URL: https://github.com/apache/ozone/pull/2874


   ## What changes were proposed in this pull request?
   
   The ContainerHealthTask in Recon currently classifies a container whose 3 
replicas are UNHEALTHY as 'MISSING'. Although the 3 UNHEALTHY replica state 
could also be potentially bad, Recon should be able to distinguish between the 
two.
   
   The above case can merely be classified as UNDER REPLICATED, with the 
metadata from Recon DB carrying the actual vs desired replica count for further 
analysis.
   
   This patch also adds support to track the bcsId reported by datanodes to 
Recon. This information is kept in the container cache, and flushed to disk 
only periodically.
