> In the following case, the data in the HDFS is lost and a client needs to put
> the same file again.
> # A Client puts a file to HDFS
> # A DataNode crashes before replicating a block of the file to other DataNodes
> I propose a metric to expose the timestamp of the oldest
> under-replicated/corrupt block. That way client can know what file to retain
> for the re-try.
