Can you address the checkstyle issue?
```
./hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/qjournal/server/JournalMetrics.java:54:
MutableStat rpcRequestCacheMissAmount;:15: Variable
'rpcRequestCacheMissAmount' must be private and have accessor methods.
[VisibilityModifier]
```
Previously with the `@Metric` annotation it had to be package-private to be
accessible to metrics2, but now it's no longer necessary and we can resolve
this by making it private.
LGTM other than that, the only unit test failing is `TestBalancer` which I
have seen be flaky in the past and doesn't look related.
