David Mollitor created HADOOP-16307:
---------------------------------------
Summary: Intern User Name and Group Name in FileStatus
Key: HADOOP-16307
URL: https://issues.apache.org/jira/browse/HADOOP-16307
Project: Hadoop Common
Issue Type: Improvement
Components: fs
Affects Versions: 3.3.0
Reporter: David Mollitor
Assignee: David Mollitor
Fix For: 3.3.0
Client is going OOM with large directory listing
{{ClientNamenodeProtocolTranslatorPB#getListing}}
I captured a memory dump and noted that each and every {{LocatedFileStatus}}
has its own copy of the user name and group name. It is sucking down a lot of
memory.
