from my point of view it is hard to provide general numbers, since it
heavily depends on
a) the type of network interconnection between the nodes in your cluster
(10/100/1000Mbit Ethernet, FibreChannel, ...)
b) the available network bandwidth, since there are many other sources of
network traffic e.g. MapReduce jobs, and
c) the replication factor itself

Our cluster has encounterd underreplicated blocks.
We understand the hdfs wil balance and restore the underreplicated blocks.
But what i would like to know , is are there references.
for example. 10 TB HDFS with 30% underreplicated blocks = ETA 5 hours
before HDFS has fixed the problem.
Are there any examples for this ?
