Jing Zhao created HDFS-4694:
-------------------------------
Summary: The SecondaryNameNode may change the inode id of root
while doing checkpoint
Key: HDFS-4694
URL: https://issues.apache.org/jira/browse/HDFS-4694
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: 3.0.0
Reporter: Jing Zhao
Assignee: Jing Zhao
SNN will call FSNamesystem#clear while merging the fsimage to its local
FSNamesystem, and the FSDirectory will be reset in this process. However, in
FSDirectory#reset, a new inode id will be allocated and assigned to the new
root.
To fix the problem, we can either pass in an inode id in
FSDirectory#createRoot, or update the root id in FSImageFormat#updateRootAttr.
