The build reports a problem due to the [spotbugs issue](https://github.com/spotbugs/spotbugs/issues/1161)
Here's a stacktrace from the build logs:
```
[2021-02-17T19:50:51.359Z] Building spotbugs database(s) using /opt/spotbugs for executables.

[2021-02-17T19:50:51.359Z] hadoop-common-project/hadoop-common cannot run computeBugHistory from spotbugs
```
Here's a [cause](https://github.com/spotbugs/spotbugs/blob/c7ead7e64382673b67e5b46a83442c846483230d/findbugs/src/java/edu/umd/cs/findbugs/SortedBugCollection.java#L1028) for this to happen.
This happened straight after substituting findbugs with spotbugs [here](https://github.com/apache/hadoop/commit/4cf35315838a6e65f87ed64aaa8f1d31594c7fcd)
@aajisaka could you please help to fix the build?
