> In Append HDFS-200 issue,
> If file has 10 blocks and after writing 5 blocks if client invokes sync
> method then NN will persist the blocks information in edits.
> After this if we restart the NN, All the DataNodes will reregister with NN.
> But DataNodes are not sending the blocks being written information to NN. DNs
> are sending the blocksBeingWritten information in DN startup. So, here
> NameNode can not find that the 5 persisted blocks belongs to which datanodes.
> This information can build based on block reports from DN. Otherwise we will
> loose this 5 blocks information even NN persisted that block information in
> edits.
