                 Key: HDFS-1108
                 URL: https://issues.apache.org/jira/browse/HDFS-1108
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
            Reporter: dhruba borthakur
            Assignee: dhruba borthakur


The current HDFS design says that newly allocated blocks for a file are not persisted in the NN transaction log when the block is allocated. Instead, a hflush() or a close() on the file persists the blocks into the transaction log. It would be nice if we can immediately persist newly allocated blocks (as soon as they are allocated) for specific files.
