[jira] [Commented] (HDFS-16958) EC: Fix bug in processing EC excess redundancy
[ https://issues.apache.org/jira/browse/HDFS-16958?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17705226#comment-17705226 ] ASF GitHub Bot commented on HDFS-16958: --- zhangshuyan0 commented on PR #5489: URL: https://github.com/apache/hadoop/pull/5489#issuecomment-1484670476 @tasanuma Thanks for your comment. I think I was wrong before. The chosen of `excessTypes` should based on healthy replicas. Assume that the storage policy is ALL_SSD, the real total block num of a striped block group is 9, and only 8 internal blocks have healthy replicas, while the total num of healthy replicas is 9. This means one internal block has redundant replicas and one internal block has no healthy replica. If we choose `excessTypes` use `numOfTarget`=9, we'll get 9 SSD storage types and can not find any redundant. > EC: Fix bug in processing EC excess redundancy > --- > > Key: HDFS-16958 > URL: https://issues.apache.org/jira/browse/HDFS-16958 > Project: Hadoop HDFS > Issue Type: Bug >Reporter: Shuyan Zhang >Assignee: Shuyan Zhang >Priority: Major > Labels: pull-request-available > > When processing excess redundancy, the number of internal blocks is computed > by traversing `nonExcess`.
