Summary: CLONE - Erasure coding: implement facilities in NameNode to create and manage EC zones
Key: HDFS-9989
URL: https://issues.apache.org/jira/browse/HDFS-9989
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: dragon
Assignee: Zhe Zhang
Fix For: HDFS-7285
As a quick first step to facilitate initial development and testing, HDFS-7347 added EC configuration in file header as one storage policy. We have discussed and [concluded |https://issues.apache.org/jira/browse/HDFS-7285?focusedCommentId=14296210&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14296210] that EC configurations should be part of XAttr. This JIRA aims to add the basic EC XAttr structure. HDFS-7337 will add configurable and pluggable schema info.
This JIRA will follow the [plan | https://issues.apache.org/jira/browse/HDFS-7285?focusedCommentId=14370307&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14370307] we made under HDFS-7285.
