Naganarasimha G R commented on YARN-5423:
-----------------------------------------
[~vvasudev], In our scenario In OM side we were ensuring before deleteting the
user any running apps are deleted, but in a general case would suggest that we
can return with a error code when application initialization fails in NM for a
given user and if its the reason for different ID, then we can check whether
any containers are running for this user and if not then we can delete the
folder recursively. Also if the user is deleted whether any further
operations(like log aggregation, in Mapred case writing intermediate
folders/files etc) will get successfully completed ?
IMO atleast appropriate error message needs to be displayed (which is missing
currently) and if possible to handle it gradaully if not immediately, thoughts?
