Kai Zheng commented on HDFS-7371: --------------------------------- It's great to have HDFS-7839, so this one will focus on loading predefined schemas from configuration file. Opened another HDFS-7859 to handle the persisting of EC schemas in NameNode. > Loading predefined EC schemas from configuration > ------------------------------------------------ > > Key: HDFS-7371 > URL: https://issues.apache.org/jira/browse/HDFS-7371 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Kai Zheng > Assignee: Kai Zheng > > System administrator can configure multiple EC codecs in hdfs-site.xml file, > and codec instances or schemas in a new configuration file named > ec-schema.xml in the conf folder. A codec can be referenced by its instance > or schema using the codec name, and a schema can be utilized and specified by > the schema name for a folder or EC ZONE to enforce EC. Once a schema is used > to define an EC ZONE, then its associated parameter values will be stored as > xattributes and respected thereafter. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
