--------------------------------
Hi,
We are managing 2PB Hadoop cluster and want to setup replication at folder
level. i.e if i change replication of /hadoop/raw_data to 2, then everything
coming into this folder should have replication factor 2.
May i know what is the status of this issue. or any new active Jira issue
related to this.

> If we can set replication factor for directory. we can modify the
> DFSClent.create() method, pass 0 for the default block replication. Namenode
> check create request, if blockreplication is 0, it will give its parent dir
> replication factor to the file blockreplication factor. This will simplify
> the administration work. You know we can set /Test or /Tmp dir's replication
> factor 2 or 1, then all their children files and dirs replication factor is 2
> or 1 defaultly.
