                 Key: HDFS-978
                 URL: https://issues.apache.org/jira/browse/HDFS-978
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
            Reporter: dhruba borthakur


HDFS should record every new block allocation (of a file) into its transaction logs. In the current code, block allocations are persisted only when a file is closed or hflush-ed. This feature will enable HDFS writers to survive namenode restarts.
