[jira] [Created] (HDFS-4800) Fix INodeDirectoryWithSnapshot#cleanDeletedINode

Jing Zhao created HDFS-4800:
-------------------------------

             Summary: Fix INodeDirectoryWithSnapshot#cleanDeletedINode
                 Key: HDFS-4800
                 URL: https://issues.apache.org/jira/browse/HDFS-4800
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Jing Zhao
            Assignee: Jing Zhao
            Priority: Minor


HDFS-4791 updated and fixed the deletion logic for reference node, but did not update INodeDirectoryWithSnapshot#cleanDeletedINode. When deleting a snapshot s, after we merge s1 to its prior snapshot s0, cleanDeletedINode is called to destroy the files/directories that were created after taking snapshot s0. However, if a node is in the deleted list of s1 because of renaming, we should not destroy the node and its subtree, but just continue the normal snapshot deletion process.
