Method used to restore deleted files on HDFS
On HDFS, deleted files are moved to the recycle bin (trash can) so that the data deleted by mistake can be restored. You can set the time threshold for storing files in the recycle bin. Once the file storage duration exceeds the threshold, it is permanently deleted from the recycle bin. If the recycle bin is cleared, all files in it are permanently deleted.

Can I directly delete inner VLAN IDs from QinQ configuration
If the switch is running V100R005 or an earlier version, one or more inner VLAN IDs in QinQ cannot be directly deleted. You must delete the current selective QinQ configuration, and then reconfigure the inner VLAN IDs that do not need to be deleted. For example, the port vlan-stacking vlan 10 to 20 stack-vlan 100 command is configured on the switch. To delete inner VLAN 15, perform the following operations: Run the undo port vlan-stacking vlan 10 to 20 stack-vlan 100 command to delete the current selective QinQ configuration. Run the port vlan-stacking vlan 10 to 14 stack-vlan 100 and port vlan-stacking vlan 16 to 20 stack-vlan 100 commands to reconfigure the inner VLAN IDs that do not need to be deleted. If the switch is running a version later than V100R005, one or more inner VLAN IDs in QinQ can be directly deleted.
