Grant Sohn created YARN-6700:
--------------------------------
Summary: Local directory health checks should not only find
problems at the local dir level but also at the usercache and filecache level
Key: YARN-6700
URL: https://issues.apache.org/jira/browse/YARN-6700
Project: Hadoop YARN
Issue Type: Improvement
Components: nodemanager
Reporter: Grant Sohn
Priority: Minor
Chmod 400 the usercache directory. The node manager doesn't notice that the
usercache is no longer usable. Since the usercache and filecache are part of
the local dir, we should extend the checks on these too.
