----------------------------------
Summary: Switch from "raw" to "system" namespace for erasure
coding policy
Key: HDFS-10916
URL: https://issues.apache.org/jira/browse/HDFS-10916
Project: Hadoop HDFS
Issue Type: Sub-task
Components: erasure-coding
Affects Versions: 3.0.0-alpha1
Reporter: Andrew Wang
Assignee: Andrew Wang
Currently EC policy is stored as in the raw xattr namespace. It would be better
to store this in "system" like storage policy.
Raw is meant for attributes which need to be preserved across a distcp, like
encryption info. EC policy is more similar to replication factor or storage
policy, which can differ between the src and target of a distcp.
