Szilard Nemeth updated YARN-11190:
----------------------------------
Description:
Given the following scenario, the placement engine does not work as expected.
A user with a '.' (dot) inside his/her username submits a job.
Let the username be "test.user"
There are 2 mapping rules:
1. The matcher matches the user with name "test.user" and has an associated
mapping rule action that sets the default queue to "root.user".
2. The second mapping rule matches the same user ("test.user") and places the
application to the default queue.
*Expactation:*
When the user with username "root.user" submits a job, the application will be
placed to queue "root.user".
*Observed behaviour:*
The application is placed to test_dot_user.
This means that the dot is replaced to "{_}dot{_}" too early so that the
default queue is set incorrectly.
I have attached a patch file that demonstrates this behaviour with 2 new
testcases along with the logs of these testcases.
