> I've observed another occurrence of this test timing out, over on
> https://builds.apache.org/job/HBase-PreCommit-GitHub-PR/job/PR-1786/3/
> The failure message is cryptic, but I think i found the issue. This isn't the
> {{HBaseClassTestRule}} invoking the timeout, it's something in the test, I
> think in the mini-cluster.
> There appears to be a timeout set in some kind of secret manager, which is
> too aggressive for this mini-cluster test. The last component of the
> mini-cluster, MapReduce, is finally available at T+273501ms -- ~4.5 minutes
> after process launch. This is how I interpret the log line
