It's all throughout FSNamesystem and related classes. I wouldn't recommend
digging in there unless you have a couple days to kill - it
So when will the replication happen ? Do you know which part of code
control the replication ? Thanks.

There is no way to force replication other than setrep. Do you have
fewer nodes than configured replicas? Hadoop will not place two

The name node will instruct the data nodes to do either remove or
create new replicas. There's nothing additional you need to do other

Hi all,
The command bin/hadoop setrepr only affect the metadata in namenode.
So How can I make it take effect on data node ? Thanks.
