Brahma Reddy Battula commented on YARN-3528:
--------------------------------------------

Following test case failure is unrelated and it can be handled in YARN-3433..

> Tests with 12345 as hard-coded port break jenkins

> A lot of the YARN tests have hard-coded the port 12345 for their services to 
> come up on.
> This makes it impossible to have scheduled or precommit tests to run 
> consistently on the ASF jenkins hosts. Instead the tests fail regularly and 
> appear to get ignored completely.
> A quick grep of "12345" shows up many places in the test suite where this 
> practise has developed.
> * All {{BaseContainerManagerTest}} subclasses
> * {{TestNodeManagerShutdown}}
> * {{TestContainerManager}}
> + others
> This needs to be addressed through portscanning and dynamic port allocation. 
> Please can someone do this.
