Barrett Oglesby commented on GEODE-7246:
----------------------------------------
GEODE-7246 and GEODE-7247 were added to address export issues. They are
mutually exclusive. If the entry value is no longer deserialized, then export
won't throw the SerializationException, and no entries will be skipped.
> Export data shouldn't fail if an exception is encountered while exporting a
> single entry

> Instead, it should log a warning in this case and skip the entry.
