Brandon Li created HDFS-6060: -------------------------------- Summary: NameNode should not check DataNode layout version Key: HDFS-6060 URL: https://issues.apache.org/jira/browse/HDFS-6060 Project: Hadoop HDFS Issue Type: Sub-task Reporter: Brandon Li Assignee: Brandon Li
In current code, NameNode allows DataNode layout version to be different only when the NameNode is in rolling upgrade mode. DataNode can't register with NameNode when only DataNode is to be upgraded with a layout version different with that on NameNode. NameNode should not check DataNode layout version in any cases. -- This message was sent by Atlassian JIRA (v6.2#6252)
