Thomas Demoor commented on HDFS-7343:
-------------------------------------

Seems to me this (partly) overlaps with HDFS-10285, which already has a design 
doc. [~drankye], as you've been active in both tickets, do you think these 
should be linked up? And what part of it is exclusive to the current ticket?

> 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.
