Previously yarn app submitted by root user are submitted "root.root" queue
by default. Currently "root" seems to be used as default queue name which is
invalid.
```
[root@04603225dae7 /]# yarn jar
/usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi 1 1000
...
java.io.IOException: org.apache.hadoop.yarn.exceptions.YarnException: Failed
to submit application_1655533034162_0001 to YARN : root is not a leaf queue
at org.apache.hadoop.mapred.YARNRunner.submitJob(YARNRunner.java:346)

org.apache.hadoop.mapreduce.JobSubmitter.submitJobInternal(JobSubmitter.java:251)
at org.apache.hadoop.mapreduce.Job$11.run(Job.java:1571)
```
Explicitly specifying queue name fixes this. Users other than root should
have no issue.
```
# yarn jar /usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi
-Dmapred.job.queue.name=root.root 1 1000
```
