[jira] [Created] (HDFS-17054) Erasure coding: optimize checkReplicaOnStorage method to avoid regarding all replicas on one datanode as corrupt repeatly.

farmmamba created HDFS-17054:
--------------------------------

             Summary: Erasure coding: optimize checkReplicaOnStorage method to avoid regarding all replicas on one datanode as corrupt repeatly.
                 Key: HDFS-17054
                 URL: https://issues.apache.org/jira/browse/HDFS-17054
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: farmmamba


Currently, when we execute countNodes method for a striped block, if a datanode has two ec blocks with different block id (because of some special cases and I will find  and fix it  laterly.). One block is LIVE, the other is CORRUPT. Current logic will compute two CORRUPT replicas because  corruptReplicas contains the datanode. We should fix it.
