[jira] [Commented] (HDFS-6835) Archival Storage: Add a new API to
set storage policy
[ https://issues.apache.org/jira/browse/HDFS-6835?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14139823#comment-14139823 ]
Arpit Agarwal commented on HDFS-6835:
-------------------------------------
Hi [~szetszwo], what do you think of making this API available to non-administrators since HDFS-6847 added support for directory level storage policies.
The use case is e.g. a MapReduce library could set storage policy on an output directory before launching jobs. Thanks.
