James Taylor commented on PHOENIX-3149:
---------------------------------------
Nice job narrowing this down, [~sergey.soldatov]. This seems like something
that would be quite feasible to have a unit test for. Would you mind adding one?
> Local index got corrupted if intermediate compaction happen during the split.

> Key: PHOENIX-3149
> URL: https://issues.apache.org/jira/browse/PHOENIX-3149
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.8.0
> Reporter: Sergey Soldatov

>
> The scenario is quite simple:
> If we trigger split after index creation when we have a lot of HFiles not yet
> compacted, the compaction may happen for part of those files and the scan
> type will be COMPACT_RETAIN_DELETES, but not COMPACT_DROP_DELETES as we
> expect in preCompactScannerOpen. In this case the regular scanner will be
> used during compaction and we get incorrectly data in the local index.
> Discussed it with [~enis] offline and it seems that the check for
> COMPACT_DROP_DELETES is not necessary and can/should be deleted.
