Kai Zheng commented on HDFS-7717:
---------------------------------
Thanks [~kaisasak] for the taking.
Do you have some thoughts ? Can you share them first for further discussion ? I
know HSM storage policy is checked and enforced by tool Mover, is the way
applicable to EC ? How the tool gets all the necessary information like EC
schema and policy to figure out the tasks and schedule them accordingly ?
Not sure MR tool is a good option, since it relies on YARN/MR service.
> Erasure Coding: provide a tool for convert files between replication and
> erasure coding

> We need a tool to do offline conversion between replication and erasure

> or act like the balancer/mover.
