Siyao Meng created YARN-9487:
--------------------------------
Summary: NodeManager shouldn't link against librt on macOS
Key: YARN-9487
URL: https://issues.apache.org/jira/browse/YARN-9487
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 3.2.0, 3.3.0
Reporter: Siyao Meng
I'm compiling hadoop/trunk native on a Mac. Found that when compiling
NodeManager it is trying to link against librt on Darwin as well - and it
failed for sure. Diff for a quick fix:

This line of code is added in YARN-8437, so this affects 3.2.0+.
Will upload the patch after I'm added to YARN contributor list.
