Review comment:
```suggestion
// check that the subset of files selected are compacted, but the
others remain untouched
List<String> filesAfterCompact = FunctionalTestUtils.getRFilePaths(c,
tableName);
assertFalse(filesAfterCompact.contains(files.get(0)));
assertTrue(filesAfterCompact.contains(files.get(1)));
assertTrue(filesAfterCompact.contains(files.get(2)));
assertFalse(filesAfterCompact.contains(files.get(3)));

Review comment:
```suggestion
try (BatchWriter bw = c.createBatchWriter(tableName)) {
for (int i = 1; i <= 4; i++) {
Mutation m = new Mutation(Integer.toString(i));
m.put("cf", "cq", new Value());
bw.addMutation(m);
bw.flush();
c.tableOperations().flush(tableName, null, null, true);
}
}
