---------------------------------------
K0K0V0K opened a new pull request, #5317:
URL: https://github.com/apache/hadoop/pull/5317
### Description of PR
The TestNMClient test methods can stuck if the test container fails, while
the test is expecting it running state. This can happen for example if the
container fails due low memory. To fix this the test should tolerate some
failure like this.
### How was this patch tested?
I run the test ~400 times in a row with zero failure.
### For code changes:

- [ ] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies
