I think we should backport this to 3.1 and 3.0 branch. One more issue is

If we can add it to one of the existing unit tests, that'd be ideal.
Otherwise, let's go with this.
The failed unit tests are unrelated.

Xiao Chen commented on HDFS-13721:

Thanks for the review Inigo, I agree adding unit test for the fix is common
best practice. Also agree ideally one should simulate the exact scenario that
caused the failure, to make sure the fix actually fixed it.
For this Jira though, it seems straightforward that when {{diskBalancer}}
object is not initialized (or if after {{shutdownDiskBalancer}} is called), any
calls to the methods which depend on it would run into NPE. We can add a unit
test to construct a {{DataNode}} object, and call
{{DataNode#getDiskBalancerStatus}} which would NPE-before, pass-after. But I
don't feel it has much value, similar to we don't test that {{diskBalancer}} is
not null after {{initDiskBalancer}} or is null after {{shutdownDiskBalancer}}
currently. :)
So I propose not to add a unit test. What do you think? Let me know if you feel
strongly about adding a unit test.

Thanks [~xiaochen] for [^HDFS-13721.01.patch].
Can you add a unit test triggering the NPE?
Ideally, we should query the JMX too.
