Throttle replication speed in case of datanode failure
Hello,
Is there a way to throttle the speed at which under-replicated blocks
are copied across a cluster? Either limiting the bandwidth or the
number of blocks per time period would work.
I'm currently running Hadoop v1.0.1. I think the
dfs.namenode.replication.work.multiplier.per.iteration option would do
the trick, but that is in v1.1.0 and higher.
Thanks.

Ack. Sorry about that guys. Need to pay more attention when I email.

Since this is a Hadoop question, it should be sent
user@hadoop.apache.org (which I'm now sending this to and I put
user@hbase in BCC).
