vinoyang commented on FLINK-7525:
---------------------------------

That is, when the user initiates a cancel request through http, when the 
configuration is enabled, the logic of the cancel is not actually executed, but 
an exception or a prompt message is returned, indicating that the cancel job 
cannot be confirmed.

> Add config option to disable Cancel functionality on UI
