Review comment:
In general, if you're not checking against the "commitTime" of the hoodie
instant, can you simply use the ActiveTime.getInstant() to get a valid commit
time instead of passing "1", "2" etc. One of the reasons is to standardize this
across all tests - all other tests use commit times in the following format ->
"000", "001" if they want to check against a deterministic commit time in the
test..
