Review Comment:
Right, the two FileDeletionTasks are independent and either can run first —
reworded. Collapsed the four per-file waits into the single wait on app1LogDir,
and moved the message into the 4-arg waitFor for the unreachable-assertion
reason.
> Fix four tests that assert on work owned by another thread

> Key: HADOOP-19979
> URL: https://issues.apache.org/jira/browse/HADOOP-19979
> Project: Hadoop Common
> Issue Type: Test
> Components: common, test
> Reporter: Jose Luis López
> Priority: Critical
> Labels: pull-request-available
>
> Four tests assert on, or tear down around, work owned by another thread
> without
> waiting for it or stopping it. All four fail intermittently, and none of the
> failures say anything about the code under test.
> * {{TestSSLHttpServerMTLS.testUntrustedClientIsRejected}} (common) expects an
> SSLHandshakeException, but the server's close races the client's last
> handshake
> flight; when the close wins the client gets a SocketException instead. 7 of 25
> runs fail. Assert that the request is refused rather than which exception
> carries it.
> * {{TestLogAggregationService.testLocalFileDeletionAfterUpload}}
> (nodemanager)
> waits for each log file to go, then asserts on the parent directory with no
> wait; DeletionService removes files before the directories holding them. Hit 4
> of the 60 most recent PRs, including unrelated ones. Wait for the directory
> too.
> * {{TestStandbyCheckpoints.testLastCheckpointTime}} (hdfs) waits for the
> active
> to hold the new image, then reads a standby's checkpoint time, which that wait
> does not cover: any standby may be the uploader, and it stamps
> lastCheckpointTime only after doCheckpoint() returns, so the interval can
> read 0
> against an expected 3000. Wait for that value to move.
> * {{TestTimelineReaderHBaseDown}} (timelineservice-hbase-tests) starts a
> TimelineReaderServer in all five tests and never stops one, leaking the
> TimelineStorageMonitor it schedules: non-daemon threads polling a minicluster
> the test has torn down. The module builds with forkCount 0, so these
> accumulate
> across its eleven test classes. Stop the server in a finally, as every other
> test in the module already does.
> Test-only change.
