Ray Chiang created YARN-5529:
--------------------------------
Summary: Create new DiskValidator class with metrics
Key: YARN-5529
URL: https://issues.apache.org/jira/browse/YARN-5529
Project: Hadoop YARN
Issue Type: Sub-task
Components: nodemanager
Reporter: Ray Chiang
Assignee: Yufei Gu
With really large clusters, the basic DiskValidator isn't sufficient for some
of the less common types of disk failures.
Look at a new DiskValidator that could do one or more of the following:
- Add new tests to find more problems
- Add new metrics to at least characterize problems that we haven't predicted
