David Johnson created YARN-7938:
-----------------------------------
Summary: Yarn task attempt listener bind port range
Key: YARN-7938
URL: https://issues.apache.org/jira/browse/YARN-7938
Project: Hadoop YARN
Issue Type: Improvement
Components: yarn
Affects Versions: 2.7.5
Reporter: David Johnson
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.
