Summary: Namenode Web UI file deletion bug
Key: HDFS-17854
URL: https://issues.apache.org/jira/browse/HDFS-17854
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 3.4.2
Reporter: Jim Halfpenny
A bug in the namenode web UI can lead to unexpected deletion of files. When a
file is selection for deletion but the cancel button is pressed in the modal
popup the modal is hidden but the event is not deleted. A subsequent delete
operation will delete all files previously selected for deletion but cancelled
as well as the the intended file.
The following steps can be used to reproduce this issue:
* Open the namenode web UI and select utilities -> Browse the file system
* Click on the trashcan delete icon next to a file
* Click the cancel button on the delete confirmation modal
* Click in the delete icon for a different file
* Click the Delete button on the delete confirmation modal
* Both files are deleted
