I am trying to trigger the false positive with the following test.
I set the following properties.
```
tserver.compaction.minor.concurrent.max=20
tserver.health.check.interval=1ms
```
Then I run the following code in jshell
```java
client.tableOperations().create("foo");
var bw = client.createBatchWriter("foo");
SortedSet<Text> splits = new TreeSet<>();
IntStream.range(1, 100).mapToObj(i -> String.format("%03d",
i)).map(Text::new)
.forEach(splits::add);
client.tableOperations().addSplits("foo", splits);
while (true) {
IntStream.range(1, 100).mapToObj(i -> String.format("%03d",
i)).forEach(row -> {
Mutation mutation = new Mutation(row);
mutation.put("f1", "q1", "v1");
try {
bw.addMutation(mutation);
} catch (Exception e) {
throw new RuntimeException(e);
}
});
bw.flush();
client.tableOperations().flush("foo", null, null, true);
}
```
I am seeing around 40 minor compactions per second while this test is
running against 2.1.0. Not seeing it run into the race condition yet. I think
I need to more tservers doing more checks against more tablets to increase the
probability of bumping into it. I am running it under Uno.
