Jing Zhao commented on HDFS-8244:
---------------------------------
Thanks for reporting this, [~harisekhon]! Actually in HDFS-7076 we already have
some discussion and a pending patch implementing this functionality (but its
jira title needs to be updated). Maybe we can reuse that jira and continue the
discussion there?
> HDFS Custom Storage Tier Policies
> ---------------------------------
>
> Key: HDFS-8244
> URL: https://issues.apache.org/jira/browse/HDFS-8244
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: balancer & mover, datanode, HDFS, hdfs-client, namenode
> Affects Versions: 2.6.0
> Environment: HDP 2.2
> Reporter: Hari Sekhon
> Priority: Minor
>
> Feature request to be able to define custom HDFS storage policies.
> For example, being able to define DISK:2, Archive:n - 2.
> Motivation for this is when integrating the archive tier on another cheaper
> storage system such as Hedvig which we are not in control of and want to
> hedge our bets in case something goes wrong with that archive storage system
> (it's new and unproven) we don't want just one copy of the data left on our
> cluster in case we lose a node.
