Subject [jira] Created: (HDFS-576) Extend Block report to include under-construction replicas
Date Thu, 27 Aug 2009 21:01:00 GMT
Extend Block report to include under-construction replicas

                 Key: HDFS-576
                 URL: https://issues.apache.org/jira/browse/HDFS-576
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: data-node, name-node
    Affects Versions: Append Branch
            Reporter: Konstantin Shvachko
            Assignee: Konstantin Shvachko
             Fix For: Append Branch

Current data-node block reports report only finalized (in append terminology) blocks. Data-nodes
should report all block replicas except for the temporary ones so that clients could read
from incomplete replicas and to make block recovery possible.
The attached design document goes into more details of the new block reports.
