                 Key: HDFS-546
                 URL: https://issues.apache.org/jira/browse/HDFS-546
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
    Affects Versions: 0.21.0
            Reporter: Konstantin Shvachko
            Assignee: Konstantin Shvachko
             Fix For: 0.21.0


{{DatanodeDescriptor.BlockIterator}} currently implements {{Iterator<Block>}}. I need
to change it to implement {{Iterator<BlockInfo>}} instead. Otherwise, I cannot filter
out blocks under construction in order to exclude them from balancing, as Hairong suggested
in HDFS-517.
