> {code} case DatanodeProtocol.DNA_TRANSFER:
> // Send a copy of a block to another datanode
> dn.transferBlocks(bcmd.getBlockPoolId(), bcmd.getBlocks(),
> bcmd.getTargets(), bcmd.getTargetStorageTypes());
> dn.metrics.incrBlocksReplicated(bcmd.getBlocks().length);{code}
> In the above code to handle replication transfers from namenode,
> {{DatanodeMetrics#blocksReplicated}} is getting incremented early, since the
> transfer will happen in background.
> And even failed transfers also getting counted.
> Correct place to increment this counter is {{DataTransfer#run()}}.
