[jira] [Commented] (HDFS-8781) Erasure Coding: Correctly handle BlockManager#InvalidateBlocks for striped block

    [ https://issues.apache.org/jira/browse/HDFS-8781?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14630612#comment-14630612 ] 

Walter Su commented on HDFS-8781:
---------------------------------

Overall it looks good.
BTW, I saw TestAddStripedBlocks#testCehckStripedReplicaCorrupt() has a thorough test for {{corruptReplicas}}. Do we need a test for {{invalidateBlocks}}?

> For {{BlockManager#InvalidateBlocks}}, currently some places track the internal block, some other places track the block group for striped block.
