--------------------------------------------

[~PhiloHe]  thanks.
{quote}iii) This project is under maintenance phase. We have no plan to move it into HDFS or somewhere as subproject, or make it become an apache incubation project.

ok.. Not sure, we can move as apache incubation project or not.

I am in favour of moving to incubation or subproject. Let's see if anybody else have any other thoughts on this.

> As discussed in HDFS-7285, it would be better to have a comprehensive and flexible storage policy engine considering file attributes, metadata, data temperature, storage type, EC codec, available hardware capabilities, user/application preference and etc.
> Modified the title for re-purpose.
> We'd extend this effort some bit and aim to work on a comprehensive solution to provide smart storage management service in order for convenient, intelligent and effective utilizing of erasure coding or replicas, HDFS cache facility, HSM offering, and all kinds of tools (balancer, mover, disk balancer and so on) in a large cluster.
