田娟娟 created YARN-7079:
-------------------------
Summary: to support nodemanager ports management
Key: YARN-7079
URL: https://issues.apache.org/jira/browse/YARN-7079
Project: Hadoop YARN
Issue Type: Improvement
Reporter: 田娟娟
Just like the vcores and memory, ports is also important resource information
to job allocation . So we add the ports management logic to yarn. It can meet
the user jobs' ports request, and never allocate two jobs(with same port
requirement) to one machine.
