Work Description: ZanderXu opened a new pull request, #4644:
URL: https://github.com/apache/hadoop/pull/4644
### Description of PR
In our prod environment, we occasionally encounter
MaxDirectoryItemsExceededException caused job failure.
```
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.protocol.FSLimitException$MaxDirectoryItemsExceededException):
The directory item limit of /user/XXX/.sparkStaging is exceeded: limit=1048576
items=1048576
```
In order to avoid it, we add a metric to sense possible
MaxDirectoryItemsExceededException in time. So that we can process it in time
to avoid job failure.
