Subject [jira] Created: (HDFS-517) Introduce BlockInfoUnderConstruction to reflect block replica states while writing.
Date Mon, 03 Aug 2009 21:56:15 GMT
Introduce BlockInfoUnderConstruction to reflect block replica states while writing.
-----------------------------------------------------------------------------------

                 Key: HDFS-517
                 URL: https://issues.apache.org/jira/browse/HDFS-517
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: name-node
    Affects Versions: 0.21.0
            Reporter: Konstantin Shvachko
            Assignee: Konstantin Shvachko
             Fix For: Append Branch


Currently when a block is created its locations are stored in {{INodeFileUnderConstruction.targets}},
which correspond to the last allocated block. With the new append design we will need to keep
track of block replicas for several blocks rather than just the last one.
