Description

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.
