Description

Currently, the Yarn task attempt listener binds to a random hight port ".setPort(0)"

For highly locked down environments, this can require a large number of opened ports between systems, which is troublesome.

 

I'd recommend either creating a new configuration item, or tying it to the MR_AM_JOB_CLIENT_PORT_RANGE.
