Subject [jira] [Created] (HDFS-9386) Erasure coding: updateBlockForPipeline sometimes returns non-striped block for striped file
Date Thu, 05 Nov 2015 21:45:27 GMT
Zhe Zhang created HDFS-9386:
-------------------------------

             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.
