-------------------------------

             Summary: Erasure coding: updateBlockForPipeline sometimes returns 
non-striped block for striped file
                 Key: HDFS-9386
                 URL: https://issues.apache.org/jira/browse/HDFS-9386
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: erasure-coding
    Affects Versions: 3.0.0
            Reporter: Zhe Zhang


I've seen this bug a few times. The returned {{LocatedBlock}} from 
{{updateBlockForPipeline}} is sometimes not {{LocatedStripedBlock}}. However, 
{{FSNamesystem#bumpBlockGenerationStamp}} did return a {{LocatedStripedBlock}}. 
Maybe a bug in PB. I'm still debugging.
