@danny0405, @zhuanshenbsj1, @stream2000, IMO, the bugfix couldn't be complex
as the pull request changed. Just modify the `getEarliestCommitToRetain` to
keep the linear cleaning with the following:
```
if (config.getCleanerPolicy() == HoodieCleaningPolicy.KEEP_LATEST_COMMITS
&& commitTimeline.countInstants() > commitsRetained) {
Option<HoodieInstant> earliestPendingCommits =
hoodieTable.getMetaClient()
.getActiveTimeline()
.getCommitsTimeline()
.filter(s -> !s.isCompleted()).firstInstant();
if (earliestPendingCommits.isPresent()) {
// Earliest commit to retain must not be later than the earliest
pending commit
earliestCommitToRetain =
commitTimeline.nthInstant(commitTimeline.countInstants() -
commitsRetained).map(nthInstant -> {
if (nthInstant.compareTo(earliestPendingCommits.get()) <= 0) {
return Option.of(nthInstant);
} else {
return
commitTimeline.findInstantsBefore(earliestPendingCommits.get().getTimestamp()).lastInstant();
}
}).orElse(Option.empty());
} else {
earliestCommitToRetain =
commitTimeline.nthInstant(commitTimeline.countInstants() -
commitsRetained); //15 instants total, 10 commits to retain,
this gives 6th instant in the list
}
}
```
WDYT?
