[jira] [Commented] (HDFS-8010) Erasure coding: extend UnderReplicatedBlocks to accurately handle striped blocks

["Zhe Zhang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDFS-8010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14385161#comment-14385161 ] 

Zhe Zhang commented on HDFS-8010:
---------------------------------

My current thoughts are:
# Move the logic of checking expected, actual, and decomm replicas into {{UnderReplicatedBlocks#add}}. This way it becomes a single place to handle both contiguous and striped blocks.
# Better placement of striped blocks into priority levels (maybe more levels are needed)

[~jingzhao] Not sure if you have already started working on this. If so please feel free to assign to yourself.
