I just fired HDFS-8074 to have a system default EC schema for you to use here as part of HDFS-7866 before I can get it done in whole. I will get the new issue done tomorrow so won't block you too long. For this issue, please find and look at all the places where we need to use the ECSchema construct in NameNode. Maybe you could list them first? Thanks. > Remove hard-coded values in favor of EC schema > ---------------------------------------------- > > Key: HDFS-8062 > URL: https://issues.apache.org/jira/browse/HDFS-8062 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Kai Zheng > Assignee: Kai Sasaki > Attachments: HDFS-8062.1.patch > > > Related issues about EC schema in NameNode side: > HDFS-7859 is to change fsimage and editlog in NameNode to persist EC schemas; > HDFS-7866 is to manage EC schemas in NameNode, loading, syncing between persisted ones in image and predefined ones in XML. > This is to revisit all the places in NameNode that uses hard-coded values in favor of {{ECSchema}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
