Feilong He commented on HDFS-7343:
----------------------------------
[~brahmareddy], thanks for comment.
i) No feature is pending. As you may know, we have made an independent project
called SSM based on this Jira's design. It is basically production ready except
some experimental features, like data sync, HA, etc.
ii) No, kafka and ZK are not required. It is recommended to deploy SSM in HDFS
cluster. The only prerequisite is user needs to deploy mysql for maintaining
SSM metadata.
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.

> 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.
