Subject [jira] [Created] (HDFS-8244) HDFS Custom Storage Tier Policies
Date Fri, 24 Apr 2015 15:26:38 GMT
Hari Sekhon created HDFS-8244:

             Summary: 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.
