Rajesh Balamohan created YARN-5551: -------------------------------------- Summary: Ignore deleted file mapping from memory computation when smaps is enabled Key: YARN-5551 URL: https://issues.apache.org/jira/browse/YARN-5551 Project: Hadoop YARN Issue Type: Improvement Reporter: Rajesh Balamohan Assignee: Rajesh Balamohan Priority: Minor
Currently deleted file mappings are also included in the memory computation when SMAP is enabled.
